Sir Paul McCartney has remembered his former Beatles band mate John Lennon on what would have been his 77th birthday.
The musician wrote he was 'reaching out to Johnny on his birthday' in a post on Twitter on Monday alongside an old photograph of the pair.
In the black and white snap, Sir Paul is reaching across a recording studio towards Lennon.
Ringo Starr also paid tribute with a photo of the pair in their Beatles days alongside the message: 'They say it's your birthday peace and love'.
Lennon's widow, Yoko Ono, said he was 'still with us and giving us wisdom and happiness when it's much needed' in her own Twitter post.
Fans also offered tributes - many of them following Sir Paul's trend by tweeting photos and videos of the pair. Lennon was shot dead outside his apartment in New York by Mark David Chapman in December 1980.
