Another random rock observation....

....brought to you by Bad Company and "Shooting Star"...
If Bad Company was not the greatest supergroup of all time, then I do believe they were definitely in the top 3. I also like a lot of the work of Cream, and more recently Audioslave too, but on the whole I think BadCo is and has always been at the top of the list.
On the other hand, hearing what I've heard on Sirius from one of BadCo's forerunners, I've said this before and I'll say it again -- for them being just a one-hit act (at least in the States), Free was a damn good rock band. Paul Rodgers has always been a hell of a singer.
