I think this guy holds the record for "most recorded session musician". He also played with /for people like Frank Sinatra, Elvis, Simon & Garfunkel, The Beach Boys, every member of the Beatles and Neil Diamond to name a few, to a total of something like 40 singles that went number 1 on the charts, 150 top-10 hits and 6 records that got a Grammy for "best album of the year". Not too many artists can put that on their CV.
If you heard songs like 'Strangers in the night', 'Bridge over troubled waters', 'These boots are made for walking', 'Mr. tambourine man', 'Mrs. Robinson', 'I get around', etc.. You've heard this dude play the drums, even if you didn't realize it. So I'd say he's the most successful unknown musician ever. Apparently he never made a fuss about himself, or wanted credit or glory for his work. He was in the rare "just glad to be a part of the team" group of guys, who show up for work on time and do a good job. That's why everybody who could, called him up first when it was time to record some music.
Unsung legend, if there ever was one.
Vaya con dios, amigo. Rest in peace.
