I don't see any mention of the song "Hans Beimler" in your list. I got it from Frank Harte after he sang it at a session in Forkhill a few years ago. I may be wrong but I think I have a recording somewhere of Pete Seeger singing it.

Just for sake of completeness, if we're not just considering recorded or professional artists, I also sing "Another Valley", Jamie Foyers and Jarama in sessions, and I'm fairly sure I've heard Tattie Bogle do Jamie Foyers on occasion too.
