Billy Preston is the only person other than a Beatle to be credited on a Beatles
album. Go to "Google" and put "Who was called the fifth Beatle?" and you'll
see Billy Preston's name come up over and over. I think you would lose on
"Who wants to be a millionaire?" if you put Epstein or Martin.

Brian Epstein was called the fifth Beatle before Preston, I'm sure. He and Martin worked with the fab four prior to Preston.
Clapton plays guitar on a number of songs, and wrote Savoy Truffle.
Keltner drums on a number of songs, most noted is Octopus's Garden.
Anyhow, I am confident that it's not Preston.
Did you ever see George Harrison's memorial concert, a year after his death? All the guys I mentioned are in the band, and they are awesome.
