A few... er.. 13 years ago, I saw Cheap Trick opening for Heart.

There were more bald and balding heads bobbing up and down than any concert I'd seen before. On the other hand, the Van Halen show I saw around that time, an outdoor show, had more young bikini-clad women than any show i've seen in a while. :-)

Most recent concert... my, that'd have to be... Adrian Belew about 1 1/2 years ago at the catalyst.
