wow bear, I'm feeling pretty good about my band knowledge, even though I don't listen to music much.
I got 16 out of the ones you mentioned, just by looking and scribbling for about 2 minutes.
Some of the one's you mentioned, like gorillas, were obvious, but I didn't know that band.
Guns n Roses
Match box 20
Butt hole surfers?
um...some others you said...
