I'm quite notorious for my view that any Fleetwood Mac without Peter Green is a cheap knockoff of a great band, and I'm standing stubbornly by that view colme what may. The greatest song to be recorded under the Fleetwood Mac name, in my humble opinion, is Man of the World.
But when Green's Mac were in there pomp there was another band in the same stable, Chicken Shack, whose lead singer Christine Perfect, the lass from Bouth in Lancashire, could take on one of the blues great Etta James's songs and do it better than Etta! Where Etta delivered it as bitter and angry, Christine was wistful and full of heartbreak. She never, again in my own opinion, recorded anytbing better.
