I find that quite odd, since I'm from Slovenia and I've heard the term. I can't really tell you where, but it must have left an impression since I even remembered it.
I'm in the upper south US, and I've never heard of it. All I could think of for street performer was Bojangles, nickname of Bill Robinson who began his career that way. (Also tried Bye-Bye for Bowie's last album - it was worth a shot.)
I think I got it from Kingdom of Loathing, a game. Haven't really heard it otherwise. - But.. how can you have a music quiz with answers that start with B and not have a single Beatles question?
Wikipedia says that after the movie "10" came out, the Ravel estate received over a million dollars in royalties for that piece, making him the best-selling classical composer at the time. It's interesting what a single movie can do for a dead man's career.
"Beethoven, Bach..."
"Don't forget Brahms please!" - Beethoven's Wig 2
Anyway, Bruckner would replace Bach if it were my list.
