Dr Hook always looked like they were enjoying themselves
Always seemed to be singing someone else's songs. A couple of Roger Daltreys spring to mind.
Sprung to mind when I was thinking of Leo Sayer as he wrote "When I Need You".
Aswad Don't turn around
Hollies Air that I breathe
Julio and Willie To all the girls I loved before.
Starship Nothings Gonna stop us now
Whitney opening song for the Olympics
I also remember a court case where he got some sort of financial rights to Radioheads Creep.
