Hi, Amos - I think the most common version of this song is "Dunderbeck." In southeastern Wisconsin, I learned it as "Johnny Verbeck," so I refuse to sing it any other way if I'm the one leading the song. It's not a song I've sung very often, so I have to use "cheat sheets" for the lyrics.
I was going to sing it at our pickers & singers gathering last Wednesday, but realized I the lyrics I had printed out didn't have and appropriately expository first verse. The one in the database ain't bad, but I prefer the one that I had known as a kid. The first set of lyrics Metchosin posted is almost exactly the same as the version I knew.
