I miss the Songbird already. When Stevie Nicks joined Fleetwood Mac one would think that Stevie and Christine would be rivals. Christine was a class act and took Stevie under her wing (literally as they lived together) and mentored her. I understand they were still very good friends.
I read a very interesting book "Making Rumors" written by the sound engineer Ken Caillat. Excellent read and Christine McVie of course was a main character. This is a good place to learn more about the Songbird. Miss you already.
