Paul McCartney is planning to release a lost John Lennon song according to reports.

A source told the Daily Express: "It has always bothered Paul a bit that they didn't finish 'Now And Then'. Although George wasn't keen, Paul always felt the song had a lot of potential.”

“He is now hoping to complete it, with him singing the harmonies to John's lead vocal. It would be very moving to hear the two of them singing one last time.”

McCartney originally planned to work on the song at the same time as he and the former Beatles we reworking ‘Free As A Bird’ and ‘Real Love’.
