Heck I'll play along. Most of my near brushes with fame are local or semi-national acts, but you might remember the names. Back in the 80's, my band opened for the Del Fuego's and Digney Fignus (Girl With The Curious Hands). Digney wasn't impressed, but the drummer from the Del Fuego's and I had a nice friendly chat about my mismatched drum set - They were decent, down to earth guys.
Coolest jazz cat I've met was Hank Crawford. Didn't play with him, but I helped him up some stairs once at the old House of Blues in Cambridge, MA. Nice guy and very thankful :)
