Some fascinating reading about Fleetwood Mac on the net in various places. I was reading a few months ago about "Rumours" and the personal battles going on behind the scenes.
The band has had lots of persoonel who have played with them at various times.
Some readers may know of a bloke called Bob Welch who played with FM prior to going solo and releasing a very succesful single called "Ebony Eyes" in 1978.
The list of players in one book I have is Mick Fleetwood, Peter Green, John & Christine McVie, Bob Welch, Lindsey Buckingham, Stevie Nicks and Billy Burnette
Billy Burnette being a rather well connected /performed musician in his own right being the son of Dorsey Burnett and the nephew and cousin of Johnny Burnett and Rocky Burnette respectively . (Wikipedia lists achievements of both in brief if you are interested. )
PS Can't be bothered to provide a hyperlink or a picture of a castle though . Sorry .
PPS Neither Bob Welch or Billy Burnette went to school in Ulladulla NSW .
