I recall Chistine with Fleetwood Mac when Peter Green and Jeremy Spencer were still with the band. They opened for Bonnie and Delaney in 1971 at Curtis Hixon in Tampa. I was fortunate to see the band at that time because it was one of the last shows with Jerremy. I was also fortunate to be able to see Duane Allman one more time; he was playing slide for B & D. It was a memorable concert.
Christine was a class act and a professional, When she and John broke up, she didn't let it affect her professional life. She had a beautiful voice and was very tasteful on keyboards.
