Well if any didn't like the OP, you won't like this...times three!
The last name I will never tell, unless I try to, then successfully hook up with him.
Nothing even close to close to fame-fame, but I got to play with a famous LA rock keyboardist from the sixties, who booked a studio on Cherokee (not theee Cherokee Studios), and was auditioning bassists.
It was my least favorite scenario, not only no drummer to interact with, but it was just he and I to boot, and while the tape was a-rollin'...yuk.
Secondly, it was one of those situations where it was a jam in A, then E, etc.
At that point, just jamming was not on my list of musical priorities unless of course it was for gig money, or the rare informal instrumental jam to keep my playing with other players type of chops up, especially in the blues genre.
Thirdly, I started figuring there could be a small chance I may play something he liked and I would never recall that it was my riff or feel if he added lyrics to it later, especially if it didn't come close to charting (99.99999% possibility on the latter), again no money at that point, yet in theory, he could benefit from it by having someone else play it on a record.
I got his number from the hall, but it wasn't paid rehearsals.
I lasted several days before I called it quits.
I don't recall what I had of his, but I had to go to his house in the Hollywood Hills across from the Bowl to return it after telling him I was bailing.
After that, he did form another band with an original bandmate and wrote some songs, one of which was used on their previous groups following album.
I think he and the original drummer finally joined the original band.
Another one was a from a drummer who Wiki sites as a session drummer.
I don't, as he was only a rock drummer who played on other famous pop-rock/rock albums and tours, as opposed to many styles other than one's own style of choice.
He had seen this act I was backing, came to an impromptu party after the gig that the front threw.
We were gabbing and he said he wanted to jam with me.
I was so thrilled, I pretty much ran to the front/host to tell him, as at the time he was sort of a mentor (until I started seeing the light!).
His response was a hand-waving "Ahh...he says that to everybody".
Deflated, I took his comment to heart and didn't talk to the dude the rest of the night, or just didn't bring up getting together.
Holding back on names only because I'm pretty sure IF any fame were to have materialized from either, the fame would not have been of the press-worthy kind in the least, more like a bassist who plays for others (my aspiration), and not exactly what the OP asked for.
This one however could have been more lucrative, with the only fame being within the industry members itself...perfect.
I was standing with a co-worker on the Warner Brothers lot, when a man in a three-piece suit approaches us and says "I am so and so's agent and he needs a script...do either one of you have anything (a scene right out of the 1940s movies!)?
Though I had worked in that biz many years prior to that, I never had the urge to see many new releases, so I didn't know his comic-client with more than a half-dozen movies to his credit at that point.
I told him I didn't know of the actor.
My partner of course knew of the guy, but didn't say anything other than that.
I said I didn't have anything, and he walked away.
Hindsight being 20-20, I've kicked myself many times for not saying "No, but give me your card and I'll rent some of his flicks that you think represent the direction he wants to head, then see if I can come up with at least a treatment for him"...but NNNNOOOOO!
Or after that (now even) write a treatment, find out who his agent is/was and call him with a "Hi, remember me?".
I mistakenly told that story at least a half-dozen times, to people in the biz nonetheless, and readily supplying the actor's name until I realized the very slim chance of someone writing a script and contacting the agent, (with or without) saying they were me, to help get their foot in the door.
Not only did I stop mentioning the guy's name in the story, I soon stopped retelling it!
