Ono, along with special guests, will be in Liverpool for the European launch of the John Lennon Educational Tour Bus on May 8 at the Museum of Liverpool. The event will be streamed live for a global audience.

The bus is dedicated to young people of Europe to provide them with free hands-on opportunities to produce original music, video, photo, game apps and broadcast projects in the bus's mobile recording studios.

Montblanc, Apple and Sony are among the companies who have contributed their equipment and funds to underscore a commitment to art, culture and education.

Ono said: "The educational bus is a huge success in the USA. But John would have been extra thrilled that it is now launching in Europe, starting in Liverpool, his home town."

People will be able to preview the bus before it sets off on a tour of the UK and Europe. The bus will also be at the Yoko Ono curated Meltdown Festival on the South Bank in London this June, amongst other soon to be announced dates.

Yoko Ono Lennon added: "I'm so thrilled that the Educational Tour Bus will be situated at Meltdown. All kids who are interested in making music and learning how to use instruments in the recording studio should come and make use of this freebie!"

Plans are underway to further expand the project to China and Japan.

Titled 'Bed Peace', the film (previously available on VHS) shows the couple's second attempt to promote world peace by lying in bed for a week at the height of the Vietnam war.

Ono said her reason for posting the documentary online is to "give encouragement and inspiration to the activists of today".

Ono and her late husband spent their honeymoon in bed at the Amsterdam Hilton, speaking to members of the press about their initiative before flying to Montreal, Canada to repeat their act of non-violent protest.

Those who visit them there are shown in the flm and include the activist Dick Gregory, Timothy Leary, DJ Murray The K and the Beatles' publicist Derek Taylor.

Writing beneath the video post, Ono said:

"Dear Friends,

In 1969, John and I were so naive to think that doing the Bed-In would help change the world. Well, it might have. But at the time, we didn't know.
It was good that we filmed it, though. The film is powerful now. What we said then could have been said now.

In fact, there are things that we said then in the film, which may give some encouragement and inspiration to the activists of today. Good luck to us all.
Let's remember WAR IS OVER if we want it. It's up to us, and nobody else. John would have wanted to say that."

The 78-year old artist posted the film on her website at the weekend. It was her intent to remove it after 48 hours but after receiving so many fan requests the film will remain online until August 21.
