In 1974, Fleetwood Mac temporarily disbanded, to be replaced with a 'New Fleetwood Mac' with neither Fleetwood nor Mac in it. Whose bright idea was it, why did they think it would work, what was the response, and what happened to the members of 'fake Fleetwood Mac'?
I went over this a bit in the second part of this answer a while back. More can be said, of course, but that at least gives an overview of the various Fleetwood Macs (Fleetwoods Mac?) that have existed.
