Paul McCartney reunited with his Beatles bandmate Ringo Starr as he celebrated the launch of Linda McCartney: The Photo Diaries on Thursday.

The music icon, 77, was in high spirits as he celebrated the release of the book in honour of his late wife at London's Victoria and Albert Museum, along with their daughters Stella, 48, and Mary, 50.  

It comes after Ringo, 79, confirmed that he was joining forces with Paul to record a cover of John Lennon's demo track Grow Old With Me, which he wrote but never recorded before his death in 1980.

Paul was delighted to be joined by his family at the book launch alongside former bandmate Ringo, who was joined by his wife of 38 years Barbara Bach, 72.

It comes after drummer Ringo recently confirmed that he and Paul will be joining forces to record a cover of one of John's last demos.

John had written Grow Old With Me while in the studio for his final record Double Fantasy, which he made before he was shot dead outside his Manhattan apartment in 1980.

It was record producer Jack Douglas who informed Ringo of the track, and he then asked Paul, 77, to play bass guitar.

The song is set to appear on Ringo's 20th solo album, What's My Name, which will be released on October 25.

Speaking about the recording process, Ringo said in a statement: 'Jack 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.

'And 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.'

Ringo then went on to say that it wasn't a 'publicity stunt', but was 'just what I wanted', as he added: 'The strings that Jack arranged for this track, if you really listen, they do one line from Here Comes The Sun. So in a way, it's the four of us.'
