Have you ever listened to the Bob Welch-era albums? They were a great band in the early Seventies. If you don't like the Buckingham/Nicks era material, you might enjoy those.I guess the fact they made it into the Sound City documentary was kinda interesting too. They were a great british blues band with Green, and a sort of bland AOR band thereafter.
Definitely RIP to Peter. Barely have ever heard any of his work (that I know of) but I like what I've heard.
