Paul McCartney wrote over 300 songs with John Lennon and two new unreleased versions of the Lennon-related track Dear Friend will be released in December.

Dear Friend was the final track on Paul McCartney and Wings’ first album Wild Life, which was released in 1971.

A remastered version, and an unreleased home recording of the song, will feature on as reissue of the  album, which will be released on December 7. Red Rose Speedway, which saw the light of day in 1973, will also be reissued next month.

"With Dear Friend, that’s sort of me talking to John after we’d had all the sort of disputes about The Beatles break up," the former Beatle has said. 

"I find it very emotional when I listen to it now. I have to sort of choke it back. I remember when I heard the song recently, listening to the roughs in the car.

"And I thought, ‘Oh God’. That lyric: ‘Really truly, young and newly wed’. Listening to that was like, ‘Oh my God, it’s true!’ I’m trying to say to John, ‘Look, you know, it’s all cool. Have a glass of wine. Let’s be cool.’

"And luckily, we did get it back together, which was like a great source of joy because it would have been terrible if he’d been killed as things were at that point and I’d never got to straighten it out with him. This was me reaching out. So, I think it’s very powerful in some very simple way. But it was certainly heartfelt."

First recorded with the bare piano and vocals during McCartney’s sessions for the album Ram, Dear Friend was intended as a peace gesture - a pipe of peace perhaps, to quote another McCartney song title - which he was now offering to his long-time pal.

The recently discovered home version of Dear Friend is one of 25 bonus tracks on the newly expanded Wild Life which features rough mixes, original single edits, B-sides, along with other home recordings.

The DVD on the deluxe edition includes footage of acoustic, home-video performances and rehearsals.
