R.i.p , I saw Christine in concert at the Patti pavilion when I was 15 , she was singing and playing keyboards with Stan Webbs Chicken Shack.
I never saw Fleetwood Mac in concert but love all their albums .
There is an amazing copy band called Rumours of Fleetwood Mac that I have seen and can highly recommend. They are playing in Swansea early next year , catch them if you can , they cover all eras of Macs music from Peter Green to Buckingham/ Nicks .
