Opinion polarising Beatles drummer Ringo Starr has brought in his old bandmate, Paul McCartney, to feature on his forthcoming solo album Y Not. Macca appears on the lead single 'Walk With Me', as well as playing bass guitar on the track 'Peace Dream'.
Speaking to NME.com Starr said: "I played him this track and Paul said, 'Give me the headphones. Give me a pair of cans'."
He continued: "He went to the mic and he just invented that part where he follows on my vocal. That was all Paul McCartney and there could be nothing better. He's a genius."
The album is due out on 12 January, 2010, and will also include collaborations with Ben Harper and Joss Stone.
