Matthew Morrison has finally unveiled his collaboration with Sir Elton John in an exclusive with Ryan Seacrest's radio show. 

He premiered the song, which is a duet and mash up of Sir Elton's famous singles 'Mona Lisa and Mad Hatters' and 'Rocket Man', and speaking to ET Canada explained what an honour it was to work with the icon:

"He gave me free reign, and it took me three days to go through his whole collection because he's got so many songs,"

"[But] it's a beautifully epic seven-minute song, and it's my favorite song on the album."

The MP3 is already available to purchase through Amazon and you can check out the track, which will feature on Morrison's self-titled debut album when it's released on May 10, here:
