I am glad to see this thread. I was looking through a box a cassettes for the car and came across a cassette that John and Jean Smith did of songs they thought Margaret and I would like. Margaret and I were booked to play for the Seattle Folklore Society in fall of '93 and spring of '94. We met John on our first visit. He liked Margaret's singing of Dick Gibbon's "Sully's Pail." We also chatted some about MacColl/Seeger's "Long Harvest" collection of ballad versions.
To make a long story short, he had a box of tapes of the long harvest when we returned in spring of '94. We only talked with him twice and he made a lasting impression. When I'm old and cackling in a wheel chair about my past, John Dwyer will be one my best memories.
