In their prime
Hey, old Yank, when did you of all people first hear Dr Feelgood? I always wondered, they were such an English, not even European phenomenon. All their US tours (opening for, eg, Kiss) went nowhere. Like The Jam, you couldn't get arrested in the States if you wore suits on stage as a rock band in the 70ies. (The Jam opened in their trademark suits for BÖC on a US Tour and had "fairies!" yelled at them until by the end of the tour Weller succumbed and the band donned jeans and T-shirts - anathema to their Mod code -, the shouts stopped and they went down better.)
I heard of Dr Feelgood first in 1976, but only via the NME which raved about these proto-Punks/pub rockers from Canvey Island. They never went beyond selling out clubs in Germany while the similarly inclined Manfred Mann/McGuinness Flint-offshoot The Blues Band filled sizable halls around the same time. I preferred the Feelgoods though.
