saw them live back in the day in a small theater (Palace Theater, Waterbury, CT) just as the first album was released. Had to be '76 or '77.
Saw many bands there (Boston, ZZ Top, Queen, Robin Trower, Kansas, J. Geils, Styx, Rossington-Collins, Aerosmith with unknown band The Cars opening, Cheap Trick, REO Speedwagon with UFO opening, I forget many since we just went to every show. My friend's father owned the place, and he and his brother had the four front rows of the balcony saved for their friends; most shows were general admission; but those friends' seats filled up fast, they always had more friends than seats lol.
Pink Floyd, Zappa, Grateful Dead, Fleetwod Mac played there too, but I was too young to go. I remember hearing advertisements about shows on the radio when I was a kid.
