I was in a band in 1973 when I was an undergrad student with a 60s-style instrumental line-up (two guitars/bass/drums/harmonica).
We played local taverns, frat parties, student bars and private parties. The pay was a joke (except for the frat events) but it was mostly fun.
The lead guitarist was pretty great and we played blues-based contemporary stuff like Savoy Brown, early Fleetwood Mac, Stones etc. The bass player was an older hippie who was still into Blue Cheer so we did things like "Babylon" and "Just A Little Bit", and I always pushed for a couple of Yardbirds oldies that I knew the harp parts for...so we did play some 60s material. As I recall, we only had a couple of original songs. The worst thing about it was that "Smoke On The Water" was a big FM hit then and we were usually coerced in playing it by the audience (although we all were sick to death of it). I usually had to sing it and shredded my voice doing it...which meant I was just banging away on my guitar until well into the last set of the night. The SIG TAU and TKE frat house beer blasts were the best...nobody was sober enough to tell when we fucked something up...lol
