I don't know if this band is forgotten in your neck of the woods but I never hear any Utopia around here anymore.
Journey
Wings
Boston
BTO
Creedence Clearwater
ABBA
ELO
How about Black Oak Arkansas?
I do have to take issue with some of these though. Stealers Wheel, Ozark Moutain, I can certainly agree with, BUt Blue Oyster Cult, Journey, ELO, Cheap Trick, Foreigner...I don't think so. These bands are the face of the 70's. On the classic rock stations here in the Northeast they are very alive and well, not forgotten (maybe even a bit overplayed), and are always on VH1 classic if anyone gets that station.
