It's hard to remember, but I think there was some dialogue regardng the famous House on an old Steve Goodman album (interview?). This was to the effect that its music had evolved from "Greensleeves" as well as that to "Streets of Laredo" and "St. James Infirmary", brought to America by Irish immigrants(This might help to date it). The dialogue then progressed to a rendition of a medley of those songs, all using the tune to "Greensleeves", an enjoyable combination which I have adapted to my own songlist. As well, I recall a sixties reference, origin long forgotten,which primarily dealt with "Sloop John B" and its origin as a sailors' ribald sing-a-long but also mentioned "House of the Rising Sun" because each of them had over one hundred and fifty known verses! Each one likely had a different writer. Public domain? No problem!
