Sir Paul McCartney is set to treat Beatles fans next month when he plays a segment of an unheard track by the iconic band.
The release will be tied in with what would have been John Lennon’s 80th birthday.
John Lennon was shot dead in New York on December 8 in 1980 when he was just 40 years old.
The song, called Just Fun, will be played as part of a special radio series airing on the BBC next month.
A documentary titled John Lennon at 80 will air on Radio 2 and contains interviews with Lennon’s youngest son Sean chat to his half brother Julian, Elton John and Paul McCartney about his late father.
Sir Paul, 78, said: “I look back on it now like a fan, how lucky was I to meet this strange teddy boy off the bus, who played music like I did and we get together and boy, we complemented each other!”
During his chat with Sean, Paul will open up about writing music with John.
He explains: “There were a few songs that weren’t very good… you know, clearly young songwriters who don’t know how to do it.”
He adds: “Eventually, we started to write slightly better songs and then enjoyed the process of learning together so much that it really took off.”
Just Fun is believed to have written in late 1957 or early 1958.
It was briefly mentioned in the Let It Be film where Sir Paul referenced writing the track with Lennon while playing truant.
While he’s yet to play the track in public, he is said to occasionally use the son during soundchecks for his solo concerts.
Lennon was shot dead outside his New York home in 1980 by Mark Chapman.
Speaking to the parole board at the Wende Correctional Facility in New York this year, Chapman, who had been denied parole on a number of occasions, said: “I just want to reiterate that I’m sorry for my crime.
“I have no excuse. This was for self-glory. I think it’s the worst crime that there could be to do something to someone that’s innocent.
“He was extremely famous. I didn’t kill him because of his character or the kind of man he was. He was a family man.
“He was an icon. He was someone that spoke of things that now we can speak of and it’s great.
“I assassinated him, to use your word earlier, because he was very, very, very famous and that’s the only reason and I was very, very, very, very much seeking self-glory, very selfish.”
