A bit of clarification. This group existed 70-72 and played shows at junior and senior high schools. We did as many assembly type shows as needed for all the students to see us in one day, then came back the following night for a(paid admission) concert. "Immigrant Song" was our opener-at as early as 7 A.M. The opening scream was, uh.........challenging. Whatever school we played Monday, the concert would be Tuesday night,
after playing 3-4 assemblies at another school Tuesday. This, of course, required moving all the gear twice on Tuesday(and each other weekday):Guitarist-Gibson SG>2 Vox Super Beatles[2 heads/2 6x12 cabs], bass man-Rickenbacker> V4B w/ 2 2x15 cabs, drummer-2 bass drums, snare, 3 mounted toms, 2 floor toms and a shipload of cymbals, organist-Vox Continental organ>Leslie cab(mic'ed into my Kasino bass amp)plus Martin alto sax and Gemeinhardt flute, and our PA which consisted of a 5 channel mixer>Dynaco preamp>Binson Echorec>Crown DC-300 power amp in a custom built cabinet-on wheels>4 Altec Voice of the Theater Utility cabs.

We were a lot younger then.

Funny aside: I remember all that crap and can't remember all the lyrics to "Old Time Rock and Roll"-which I sing on each of our gigs.
