My first real big rock show was seeing Zappa with Flo & Eddie in the old (but still not yet gone) Pittsburgh Civic Arena, using the folding-out opera stage, not a big flat one built on the hockey rink floor. They didn't use the opera stage much, and finally quit using it because they were afraid it might not fold up again. They stopped opening the dome roof, too, after a few decades, for fear they couldn't get it to shut. The arena was too far ahead of it's time, meant to be a showpiece of Pittsburgh industry. It's 50 years old and they're voting on whether to wreck it in early February.

Anyways, Zappa did... Billy the Mountain! It was, like, their newest song. What a great show! Don't remember a lot about it, it was the '70s after all...
