Wow, yes, a big loss.
I Have 2 early albums by Chicken Shack, both on Blue Horizon, when she was known as
Christine Perfect, before she married John McVie and joined Fleetwood Mac in 70'.
Those 2 albums are:
40 Blue Fingers, Freshly Packed and Ready to Serve (1968)
O.K. Ken? (1969),
I was a huge John Mayall and the Bluesbreakers fan, then loved the early Fleetwood Mac (Peter Green and Bob Welch days).
She added a lot to Fleetwood Mac in 70, but I have the 1968 album "Mr. Wonderful" where she plays keyboards.
Such a rich history there, and the music was magic !!!!
