I found this discussion thread by doing a web search on Ding Dong Dollar, and wish I'd found it sooner. I work with the Folkways Collection at the Smithsonian and am doing a study on this recording, looking at the correspondence that's in our archive. We have correspondence between Moses Asch and both Hamish Henderson and Morris Blythman. Fascinating stuff! It also rounds out what I know from having interviewed Marion Blythman, Ray and Archie Fisher, Norman Buchan, Hamish Henderson and others in the 1980s about the anti-Polaris songs.
