I no longer recall whether or not SB received much airplay @ Chicago. Probably not @ the early 1970s as AOR programming didn't quite "gel" until around 1974. And besides, we had a few local Blues ensembles who represented the genre quite capably, thank you.
Past that, I enjoyed SB and collected their early LPs, @ least the debut through/including Hellbound Train. They dropped from radar after that.
FWIW, while Foghat were known in/around Chicago, they didn't achieve large(r) venue status until the "Slow Ride" (1975?) phase of their career, and even that was a short-lived "success" @ our town.
