Sir Paul McCartney has confirmed a 14-minute long Beatles track many thought was a myth does exist - and says he wants the public to hear it.
He told BBC Radio 4's Front Row the track - called Carnival of Light - was not released because the other Beatles thought it was too "adventurous".
The full interview will be broadcast on BBC Radio 4's Front Row on Thursday 20 November at 1915 GMT.
