Yes, WLD, highly recommended if you're at all interested in MacColl's legacy - as you obviously are.

Nevertheless, I would also echo Fred McCormick's comment that we do need more info. on Ewan's theoretical and practical work on singing and singing styles. I attended one of the singers' workshops that he and Peggy ran back in the late 60s. That weekend made a vivid impression on me and the broad outlines of what I learned remain with me to this day. I just wish I'd taken detailed notes (although it probably wouldn't have been appropriate) because the memory of specific details have inevitably faded with time.

Unfortunately, Ewan never got round to publishing anything. I do know that many of the Critics Group sessions were taped ... perhaps one day a selection could be published in some form or other?
