Condemned Buildings With Rats
Unseen band from the "Free Room & Rock" (1981) episode of syndicated television series The Music Shoppe, featuring the adventures of a rock band of Indiana high-schoolers who rehearse in Gary Crosby's (yes, Bing's son) music store of the title.
Crosby's old agent, Spence (veteran character actor Jesse White), comes around trying to get Gary to tour again so he can get his sweet, sweet ten percent, but Gary's not interested. Spence gives him some tickets to his latest act, this band with a wacky name.
One character says: "That was the worst concert I ever heard in my life." Also, they wear pants on their heads as part of their stage act.
