Still ... I remember that gig, too. We were pretty green all around. We backed our vehicles up to the loading dock and discovered that, due to union rules, we weren't allowed to unload or touch our equipment ... it all had to be done by union employees (this IS Detroit, after all). That was a bit perplexing and frustrating -- we were just too green to understand how these things work in the big city. None of us got "written up" by the union, at least, but, if I remember rightly, we had to wait and worry about our gear until it was finally delivered to the room in which we were to play.
The crowd were pretty bizarre, too, but not all that extreme for any sci fi con I've attended. The costumes were sometimes amazingly accurate to the TV show, or just plain odd, and there was a certain sense of humor to the whole thing that I enjoyed. Events like that just aren't that well known to the main stream of society, nor are they large enough to involve large numbers of people, so most people are never aware that they exist. But the ARE a lot of fun.
I agree that the fans probably didn't know what to expect from us, and our newness as a band ... well, I'm sure the performance was acceptable, but possibly barely so. Maybe we were even too far out for many of the assembled Trekkies. Some people always take themselves too seriously, unfortunately, but it was a cultural happening, and a gas overall.
Good times, man!
Keep on jammin'! - Mumbles
