They went through a lot of line-up changes post Peter Green. The Peter Green era is perhaps my favourite period. The two best albums after Green's departure and during Welch's time were, IMHO, the '71 Future Games and '72 Bare Trees albums. Fabulous cuts all, and tough to choose one or two. These were the last albums with Danny Kirwan, who was supremely superb in his own right.
Woman Of A 1000 Years from the Future Games LP.
