Over recent years if I played The Wild Rover the odd person now and again mentioned that the chords and melody are identical to a song originating in Hamburg in Germany. They were unable to be more specific about the lyrics (if they were the same) or title of the German version. But they seemed adamant that it was the same melody and from the few lyrics they heard, didn't sound like the same song.

Does anyone know anything about this? Has anyone heard this other version?
