I started attending the F-1 Grand prix races in Watkins Glen from 1964 and went every year until I left NY in 1968. I saw plenty of famous now-dead racers like Jim Clark, Jack Brabham, Dan Gurney (he's still around); one of my favorites, Graham Hill; Ritchie Ginther, Pedro Rodriguez, and Lorenzo Bandini. And I have a Watkins Glen F-1 race ticket w/Stirling Moss's autograph on it, that he begrudgingly signed for me. No I never met a Beatle there.
I did see Bob Seger sing in MI plenty of times in the 1960's and early 1970's and one of my friend's was well acquainted w/a member of Bob Seger's business group, a woman who was her maid of honor at her wedding. The woman was a looker, tall, slim, black hair, white skin. "Ramblin' Gamblin' Man" was a big hit in 1968 and I saw him play it live back then in MI nightclubs from then on, before he played the big venues.
I saw Wayne Cochran sing "Goin' Back to Miami," in Miami FL, which was a great concert. Never met the man. He had a great voice, and put a lotta energy into his shows.
Another one I
did meet in about 1970 was George Clinton, who put on one of the most high-energy shows I ever saw, right up-there w/Sylvester Stewart in his prime, who I once saw in Cobo Hall-Detroit one weekend, and the next weekend in Kalamazoo, MI. Trivia: what was his (S. Stewart's) stage name? No-fair googling! And, bonus round! What was the name of George Clinton's band (he changed the name a bit over the years)?
I did watch from the front row while BB King sang, among others, "Lucille," on his Gibson, in the city where "Lucille" was built. That was in about 1971 on the rooftop of a parking garage in MI.
Back around 1977 or 1978 my ex wife and I met George Harrison at Watkins Glen, at a Grand Prix F1 race.
Back in the late 1960's I was on a stage singing (of all things) "Hey Jude" with a guy who was a relative unknown at the time - Bob Seger, of "The Bob Seger System".
Drank cheap whiskey with Wayne Cochran (the king of blue - eyed soul) backstage after a show in Buffalo, back around 1974.
