If you search for "Ging Gang" on Spotify, you'll come up with all sorts of variations. Above, Keith A mentions a version by a 70s pop band - I wonder if that was the Tremeloes version. I couldn't understand much of it. There are two (apparently German) groups that have disco versions of the song - Der Trickser and Inner Kneipe. Most of the other versions sound like polkas.

I think I heard in Scouts fifty years ago that the song was written by Baden-Powell, but that could well be a fable. It's not a song I sang as a Boy Scout. I had heard of it, but never heard anybody sing it. Our Scout Songbook Index doesn't show the song in U.S. Scout songbooks.
