Paul has today unveiled a new film in his 'Pure McCartney VR' documentary series. The virtual reality films - created in partnership with Jaunt VR - focus on a selection of songs from his forthcoming release, Pure McCartney. In this third instalment of the series, Paul takes us behind-the-scenes of 'Early Days', which features on his 2013 album NEW.
The 'Early Days' film sees Paul talk about writing songs with John Lennon and how they hoped that someone, somewhere might listen to them. George Harrison joins in when they needed another guitarist, and Paul knew him from school. And then Ringo Starr - a local drummer the band met whilst in Hamburg - completed the line up with Paul stating, "This is it - we are The Beatles".
Elsewhere in the documentary, Paul discusses a mystical party with Bob Dylan, and appearing on The Edi Sullivan Show in front of 73 million people!
