I have lots of cassette tapes and CDs that John Dwyer picked up at events all through Western Washington, BC, Canada, and down into Oregon. If you come up with a little more information maybe I can find something in the shelves here. Where is Kevin Wald? Is he in the Pacific NW and would the group be local, or do you have to search further afield? (I also have a lot of tapes of the Seattle Song Circle sessions he attended.)
