Martin, just got a copy of a tape Dan sent to Shea Walker (a Dubliner), who Dan had originally heard 1 verse from, Shea's tape has a fellow singing it to Dan as you have it & also stating he hadn't sung it in 20 years. I don't know if this is your same Tom, but he says he has it form a medical photographer Dave Smith who helped run a kitchen club (?) from 1962-1965. That's about it, Shea can't recall where he got the 1 verse from. Barry
