For all the bad, there's always a good one... My band opened for Tommy Keene in the mid 80's. They went a little over on their sound check, and there was not much room on the small stage. After the sound check, the drummer struck his own kit, so our guy had room to set up. I can't recall if their first major label album had come out at the time. But I remember how cool his drummer was, and have always tried to be as cool to others, whenever possible.
Yeah. These stories make me realize how lucky we've been.
All the headliners we've played with have been really accommodating and supportive. Really cool to hang out with, too.
So we treat our openers the same. That's what it should be about!
