Getting close to closing shop on this one but here's one more....
Back around 1992 I went to a small live house in Seattle to check out this alternative rock band The Lemonheads as they had a song that was playing on the radio I liked (see below). They also did a cover of "Mrs. Robinson" which was interesting.
It was a cheap entry and could drink beers while taking in the scene. Upon entering, lo and behold there was Johnny Depp sitting at a table pushing their paraphernalia so I was surprised to say the least. Had a brief chat with him and I guess he was friends with them at the time. Not something you see everyday.
