(Now, THAT'S Trivia #12) Boogie Days

Today's trivia question comes from the world of music, an area of pop culture that I've sadly sort of neglected..maybe it's because just about the only radio I listen to these days is NPR news and talk. My favorite music remains the songs I grew up with; the music of the 1970's and 80's, which is also the music that I spun during my brief career as DJ back in the late 80's/early 90's.

So, today's question is:

On Elton John's version of the Beatles' Lucy In The Sky With Diamonds, a guest musician plays with John and is credited as "Dr. Winston O' Boogie." This, obviously, is a pseudonym. Nobody names their kid Winston anymore. What was the good Dr. O'Boogie's real name?
