Kate, my darling. I know that you are a Fleetwood Mac fan as I am also. However, I don't know if your are a fan of the Bob Welch era of the Mac, which was just prior to Buckingham/Nicks.
Anyhoo, I was listening to some early 70's Mac, most notably the Mystery to Me album, and I fell in love all over again with this fantastic song. Have you ever heard of it?
