You went to see Devo?
So did I, but I hesitate to admit it. I had to take my sister (10 years younger than me) because my wife thought I was nuts. Really fun show. The crowd was into it and many were in interesting costumes (recall one group of guys in old-fashioned tuxedos and instead of heads, these opaque white globes). And they did a bunch of music videos that were particularly interesting because at that time MTV and the term "music video" had not been invented. Warm-up music that was cool. Kind of Blue Man Groupish.
