My HS band played at Boston's Symphony Hall with Keith Lockhart. Martin Short was there to perform, and Helen Hunt was in the audience. I stole her pencil. (hahaha)
I also met that almost-but-not-quite-a-hit boy-band "C-Note" when they came to my local mall years ago. I was shopping with my older cousin and one of them asked for her number.
I also met Matthew Broderick, Vanessa Williams, John Stamos, and Christopher Seiber (the dad from "Two of A Kind" *he's on Broadway now*) just by hanging around before and after shows in New York City. Most people don't realize that most of the theaters don't have a "backstage" entrance/exit. The actors walk right out of those big doors with the pictures on them!
If anyone here is/was a drummer in a marching band, I'm good friends with Tom Aungst (the Vic Firth guy). He teaches the Cadets.
*edited to add: OOH! I can't believe I forgot to include meeting Mikhail Baryshnikov at a dance conference! Oh, he is so AMAZING!*
