The customized VOX guitar sold for double the predicted amount during the music auction at Times Square's Hard Rock Café on May 18 and the auction house, Julien's Auctions, explained:

"The rare offering of a VOX guitar played by both John Lennon and George Harrison is what rock & roll legends are made of."

Harrison rehearsed 'I Am The Walrus' on the instrument while Lennon used it in a video shoot for 'Hello Goodbye', both of which feature on 1967 album 'Magical Mystery Tour'.

The guitar was custom made by Mike Bennett and Dickey Denney, and was given to "Magic Alex" Mardas, an engineer at Apple Records and close friend of the Beatles, back in 1967.

As previously reported, the veteran crooner and the 'Born This Way' icon are due to team up in the near future to record an album.

Speaking to the AP, Bennett said that the record will be "swing" orientated, adding that he thinks Gaga is a big star. He said:

"We're doing a big swing album and I'm looking forward to it. She's a wonderful person and a great talent."

Bennett continued: "We have it all worked out already on paper and we'll just talking about it and we can't wait to do it. She's quite different."

The somewhat unlikely pair have previously worked together on the 2011 track 'The Lady Is A Tramp'.

Performers:
Dierks Bentley is an ACM Award-winning singer/songwriter who has forged his own brand of country music combining classic country songwriting, influences of bluegrass instrumentation and the energy of rock & roll. Bentley's sixth studio album Home, released in 2012, debuted at #1 and has spawned three chart-toppings hits, marking 10 career #1 songs as a singer and songwriter. He is currently on the "Locked & Reloaded Tour" with longtime friend Miranda Lambert . On April 6, Bentley will headline the ACM Party for a Cause Festival, a two-day outdoor music festival during "The Week Vegas Goes Country®," and on April 7, will perform at the ACM Fan Jam.

Keith Urban is a seven-time ACM Award winner, who has sold more than 15 million albums. This spring will bring the release of brand new music, his fourth annual All For The Hall benefit, a highly anticipated tour, which gets underway this July, and continued filming for American Idol.  He has celebrated 14 No. 1's, including 28 Top 5 hits and has had five consecutive platinum or multi-platinum albums.  In 2010, he was given the Academy's prestigious Jim Reeves International Award in recognition of his outstanding contributions to the acceptance of country music worldwide.  

Lady Antebellum is an ACM award-winning trio comprised of Hillary Scott , Charles Kelley and Dave Haywood .

The track hit big out of the gate, becoming the trio's highest-charting debut on the Country radio charts.

Pitbull has risen to become a global superstar as both a recording and performing artist. The Miami native recently added to a long and growing list of hits with his first # 1, "Give Me Everything." At the same time, his world tour sold out concerts in Latin America, Canada and Europe, before bringing the party to the United States, Japan and Australia. Pitbull's new single "Feel This Moment" featuring Christina Aguilera is a worldwide smash and "Don't Stop The Party" was another global radio and video hit that are featured on his new album, Global Warming.  It's the highly anticipated follow-up to Planet Pit, which earned critical acclaim and enjoyed massive commercial success with sales of more than 1.7 million albums and 19 million singles. "Don't Stop The Party" and "Feel This Moment" come on the heels of Pitbull's 2 million-selling single, "Back In Time," the chart-topping anthem from the action-adventure-comedy Men In Black 3.

About Tim McGraw 
For 20 years, McGraw has been providing that kind of powerful connection with his audience. With Two Lanes of Freedom, his new album—and first release for Big Machine Records—the singer is covering his broadest emotional range yet, with a set of songs that looks forward and back, gets deep and gets loose, and reveals that even the biggest stars can continue to grow with consistency and maturity.

In his record-shattering career, McGraw has sold more than 40 million albums, and dominated the charts with 33 No. 1 singles. Since the release of his debut album in 1993, he has won three GRAMMYs, 15 Academy of Country Music Awards, 12 Country Music Association Awards, and 10 American Music Awards, while simultaneously maintaining a parallel career as a successful actor in such films as "The Blind Side," "Country Strong," and "Friday Night Lights"—as well as hosting Saturday Night Live, a rare honor for a singer in any genre. McGraw has never been afraid of breaking new ground; over the years, he has collaborated with musicians from Nelly to Tony Bennett to Def Leppard and Ne-Yo.

Camden, which is home to many musicians along with well-loved live music videos, is set to be the host for the strip and will twin with Hollywood to honour some of the UK and the world's most popular acts.

30 plaques are confirmed to be laid down and some of the first honourees will include the late Amy Winehouse, The Who and Madness.

The NME reports that acts who will be represented on the walkway are due to be grouped into the following categories: "innovative artists, influential artists, icons, unsung heroes and industry figures."

Lee Bennett, from The Walk Of Fame, told the BBC News that it's a fantastic idea to openly celebrate music in England's capital: "We hope this will be the highest accolade in music. This is an international brand not specific to Camden, but it is in Camden as we truly see it as the world's rock and roll capital."

Watch Winehouse's video for 'Tears Dry On Their Own' here:

As previously reported, the veteran crooner and the 'Born This Way' icon are due to team up in the near future to record an album.

Speaking to the AP, Bennett said that the record will be "swing" orientated, adding that he thinks Gaga is a big star. He said:

"We're doing a big swing album and I'm looking forward to it. She's a wonderful person and a great talent."

Bennett continued: "We have it all worked out already on paper and we'll just talking about it and we can't wait to do it. She's quite different."

The somewhat unlikely pair have previously worked together on the 2011 track 'The Lady Is A Tramp'.

Bennett was speaking to the Metro when he made the revelation, stating that he spoke to her parents about the potential collaboration.

They said that Gaga would like to make a whole album with Bennett - something which he is "looking forward to". He said:

"She's a very talented person. I was with her parents recently and they said she'd like to make an album with me. I'd like to do that, too. I'm looking forward to it."

Bennett meanwhile commented on a naked sketch he drew of Lady Gaga last year for charity, which managed to raise $30,000. When asked why he did it, Bennett replied:

"It was the right thing to do. I paint every day. Some days I paint models nude – like Michelangelo when he did the Vatican. The sketch I did of her sold for $30,000 and the money went to her charity."

Winehouse was in no hurry to release the material. Instead she hoped to release a jazz album with a supergroup, that was to include The Roots member, ?uestlove. There were many other contributors rumoured to be involved, including the saxophone player Soweto Kinch.

Only two of these songs were recorded and will feature on her upcoming album, 'Lioness: Hidden Treasures'. 

?uestlove is set to feature on one track on the album, called 'Half Time'.

The last recording the 27-year-old committed to tape was a duet with Tony Bennett, called 'Body and Soul', and was released in September to benefit the Amy Winehouse Foundation.

The album will be released in early December. Listen to the lead single from 'Lioness: Hidden Treasures', 'Like Smoke', and a behind the scenes look at 'Body and Soul' below:
