I worked with a group of students who were playing songs like Tom Sawyer by Rush, and The Ocean by Led Zeppelin. These are hard for adults, let alone teenagers.
If you bellied up to the bar at the Show Ring in Brewer, or pulled the van into the KOA campground in Ellsworth for the weekend back in the late '70s or early '80s, chances are one of these bands were playing there that Saturday night.
