The Beatles are nearly back together again as Ringo Starr has teamed up with Paul McCartney to record a version of a song from a lost demo recorded by John Lennon.

Less than a year before his death, Lennon penned Grow Old With Me during the sessions for Double Fantasy, the final album he made before he was murdered outside his New York apartment on December 8, 1980.

The track will feature on Ringo Starr's 20th solo album, entitled What's My Name, which is set for release on October 25.

Starr said: "(Producer) Jack (Douglas) asked if I ever heard The Bermuda Tapes, John's demos from that time. And I had never heard all this.

"The idea that John was talking about me in that time before he died, well, I'm an emotional person. I just loved this song. I sang it the best that I could. I do well up when I think of John this deeply. And I've done my best. We've done our best.

"The other good thing is that I really wanted Paul to play on it and he said yes. Paul came over and he played bass and sings a little bit on this with me.

"So, John's on it in a way. I'm on it and Paul's on it. It's not a publicity stunt. This is just what I wanted. And the strings that Jack arranged for this track, if you really listen, they do one line from [George Harrison's] Here Comes The Sun.

"So in a way, it's the four of us."
