Fab Four fans will be happy to hear that Paul McCartney has joined former Beatles bandmate Ringo Starr on the first single of forthcoming studio album "Y Not". The song that McCartney appears on is called "Walk With Me" and will feature both legends signature vocals.

The press release says about the new single:

"Walk With You" is a moving, even spiritual meditation about the lasting power of friendship, and McCartney's inspired participation on the track was a testament to McCartney's generosity of spirit and musical talent. "Paul was doing the Grammys, so he came over to the house and was playing bass on `Peace Dream." So I played him this other track and Paul said, `Give me the headphones. Give me a pair of cans.' And he went to the mike and he just invented that part where he follows on my vocal. That was all Paul McCartney, and there could be nothing better. He makes it bigger and he makes it fuller. It makes the song like a conversation between us, and that was Paul's idea to do his part one beat behind me. That's why he's a gen-i-us and an incredible bass player."

Starr's new album features a lot of big names with collaborations coming from the likes of Joe Walsh, Joss Stone, Van Dyke Parks, Ben Harper and Richard Marx. Y Not hits stores on January 12th.
