I realize I'm jumpin' in real late on this one; I just got on board after being away from Songfacts for a long time...
Can't believe nobody mentioned (or remembered?) the 70's glam-rock band Angel! (Punky Meadows, Frank Dimino, Greg Giuffria, Barry Brandt, Felix Robinson). Not only did they have some really great rocking songs, their LOGO was the only one that I recall that was perfectly legible upside-down! That was pretty much everyone's mindset at the time, come to think of it!
(Damn, can't figure out how to show the logo here - I attached...)
