As far as I am aware, no other well-known band has done this thing, that is, to release two eponymous (self-titled) albums. The reason for this is obvious – to speak of the album “Fleetwood Mac” by Fleetwood Mac is ambiguous, as the phrase applies to two completely different things. It is a bit like talking of “1.30 a.m.” on the night the clocks go back here in the UK; there are two such moments.
So, why did the group do this? What happened? My view is that this was a deliberate murder and rebirth of the band, which involved airbrushing out all the history that had happened previously under the “Fleetwood Mac” banner.
This was not a personnel change, as had happened so often from 1968 to 1974. Rather, it was the launch of a completely new group.
What seems to have been going on behind the scenes is something like this. Mr Fleetwood and the McVies had become a little 3 person management committee (as the name of the group suggests they are entitled to do) while on tour in the USA, upon meeting a Californian couple comprising a guy with a girl’s name and a girl with a guy’s name, who had obviously for some reason or reasons impressed them greatly. The long-serving Californian Bob Welch was removed (as part of the airbrushing; he would at that time be deemed never to have existed).
And here we have a brand new five person group, of whom two are girls.
