Re: Fleetwood Mac
I go back quite a while with Fleetwood Mac. Although not as far back as the earliest Peter Green works, but I do remember 'Oh Well' being played on radio many years ago. I've always liked that song, so much so that I made a point of buying the CD, specifically for that song. I was pleasantly surprised to hear other songs on that release that were very good, as well. With most of the earlier material being blues orientated/inspired, some songs may not be for everyone, but there is really good blues-type jamming on some of the earlier albums, imo.
I do find it interesting, not only with some Fleetwood Mac songs, but other artists' as well, that many of the original versions of what are now considered classic songs that were possibly first heard being done as a cover version by another band some years later (i.e., Black Magic Woman, Oh Well, Green Manalishi).
The first Fleetwood Mac album that I did hear in it entirety was of the pre Buckingham-Nicks line up. Imo, Fleetwood Mac did become their most commercially successful with the Buckingham-Nicks line up, but there were quite a lot of internal 'things' going on within the band and the members personally that did both contribute and add more interest to many of their songs and music, too!
Kudos to Flower

for the nice addition of the earlier years and I also agree with LG! Judas Priests' cover of Green Manalishi is fantastic, more so with their live version!
