I was recently looking at the album cover of The Beatles "Sgt Pepper's Lonely Hearts Club Band" album and realized TP is one of the faces on the cover. He's right behind John Lennon and below Tony Curtis, third row down.

As a fan of The Beatles... confirmed!

He's identified in the 80s CD booklet. Don't have the new remaster.
