More today from the CD insert, being the potted history on Page 5:
“Danny Kirwan – Guitar and vocals
Joined Fleetwood Mac 1968 from Bolierhouse, ex Brixton Blues Band.
Christine McVie – Piano and vocals
Joined Fleetwood Mac in the Summer [sic] 1970, from Chicken Shack.
Bob Welch – Guitar and vocals
Joined Fleetwood Mac in Spring [sic] 1971 from various California R&B groups.
Mick Fleetwood – Drums
Original member of the group with Peter Green, 1967. From John Mayall’s Bluesbreakers, and Shotgun Express with Rod Stewart, to name a few.
John McVie – Bass
Founder member of John Mayall’s Bluesbreakers. From 1963 to 1967. Joined Fleetwood Mac from its inception.
Personnel changes to date:
Mick Fleetwood, Jeremy Spencer, John McVie and Peter Green started group in 1967. Danny Kirwan joined later. Then Peter Green left in 1969. And then Christine McVie joined. Then Jeremy left six months later. Bob Welch joined in 1971.”
There is of course at least one error in this description of what had happened, in that Peter Green quit the band in 1970. A full discussion of all this stuff can be found far above in this blog. Nevertheless, it seems clear that Christine McVie joined the group before Bob Welch did, and it is from that interim period that I believe the song “Dragonfly” comes.
