Can we have a recap here
British band
in 70s
Were they actually big?
What kind of muisc ? Metal, rock, progressive ? Like Slade, Cream, UFO ???? Can't be like all of them and Blimey UFO ! I'd forgotten about them
Lead singer has a gravelly voice but it isn't Lee Marvin. Like Jo Cocker ? Joe Walsh ? Oh no, British. So that's Steve Miller out. Yes ? As in the band Yes.
Were they 'popular' ? On Top of the Pops ?
Free - they were good

What kind of instruments ? Straight stuff or keyboards and 'extras'?
