Thanks for that Les. It has long been one of my favourite ever Fleetwood Mac songs. It's a dark, brooding masterpiece with stunning musicianship. Can you imagine a band trying to record something like that without a click track nowadays? It is even more poignant when you bear in mind that it was the end of Peter Green's most potent period as an artist. I don't think either he or the band ever scaled those sort of artistic heights again.
