I saw a video by Pete Wylie recently where in a preamble to performing "Remember" by Shambeko! Wah he explained his reasoning behind the various name changes for the various incarnations of Wah! over the years which you can see here.
There's been two Fleetwood Mac's taking their name from Mick Fleetwood and John McVie but formed and led by Peter Green in their first incarnation, there was then a transitional period (read here) and eventually Mick Fleetwood met the duo Buckingham Nicks , and Lindsey Buckingham became the bands driving force with admirable support from Stevie Nicks and Christine McVie producing "Rumours" and "Tusk", the latter being my favourite Mac album and was remade by Camper Van Beethoven .
I also love the Buckingham Nicks album which I think is only available as a bootleg CD for some reason but you can hear why Mick Fleetwood wanted them in Fleetwood Mac.
The point of this post is given that Peter Green formed the band why was it named after the drummer and bassist? I mean Green Manalishi would have been a great name for a band though that was the last song that he recorded with the band.
I will share the Buckingham Nicks album which is available on YouTube with you so you can judge for yourself.
