Yes, the guests were terrible. All of the concert footage was shot during Memorial Day weekend 1989 at the pacific amphitheater in Costa Mesa, ca. This was the second show of that summer's beach boys/Chicago tour. Other footage was shot later that week at universal studios in Los Angeles. The series ran during the summer of 1989 in the us on syndicated stations. The campfire scenes are a must see
Stevie Ray Vaughn did a pretty cool guest spot one week.
I must say I do not remember that. Here is what I do remember--Roxette, Richard Marx (with the guy who played Jason from the "Waltons" on guitar) a really bad comedian named Richard Jenni who I think was also on Star Search, and some guy with a puppet.
