I really can't say I have a lot of time for Free. But they were the darlings of the (British) press for a time, so there you go.
I have little time for Bad Company either. I remember more than I care to, including some NZ band doing a cover of theirs: Feel Like Makin' Scones.
But I love the Free song Wishing Well, and when singer Paul Rogers does it in Bad Company, well it all comes back. And you don't even have to like either band.
