Sir Paul McCartney is convinced late rocker John Lennon took on the form of a white peacock and visited his former THE Beatles bandmates during a recording session for his song Free As A Bird.

McCartney, George Harrison and Ringo Starr performed backing music to accompany an old Lennon vocal recording to produce the 1995 single to accompany the release of the ANTHOLOGY series.

But when the three former Beatles posed outside the recording studio for a photoshoot, a white peacock mysteriously joined them.

McCartney recalls, "That's John. Spooky, eh? It was like John was hanging around. We felt that all through the recording."
