I can't seem to find a discussion of this song, not even a mention actually. I tried searching both DT and Forum for "My hand on my", "Mine hand on", and "Mein hand on" without success.

As a kid I always heard it and sang it (mostly at Boy Scout camp, I think) in faux-deutsch accent. I'm having a really hard time remembering the specifics. The question arises because I was singing

Mein hand on mein head, voss is doss here?
Doss is mein pea-pecker, my mama dear.

and my wife overheard me, and had never heard the song (despite having done time in both Girl Scouts and Campfire). We were mutually amazed, but I couldn't think of how the whole thing went, and now I'm stumped by my failure to find it on the 'Cat...

Google gives a number of versions, but none shows any vestige of dialectal teutonicism. I can no more imagine singing this in normative English than I could "John Jacob Jingleheimer Schmidt" or "There was a little Dutchman" or "Lutefisk, O Lutefisk"...
