Idle Race:

once featured vocalist Dave Walker who went to Savoy Brown and then on to Fleetwood Mac (the pop Mark II) - from which he allegedly was sacked, making the band sound too much like Savoy Brown... Life ain't fair sometimes.

Idle Race also once featured Bob Lamb and Bob Wilson, later of Steve Gibbons Band. And Steve Gibbons himself has been a member of Idle Race, I'm told!
