Donovan's "Universal Soldier" Lyrics

I know Buffy St Marie’s lyrics say “Dachau” and I know Donovan sings “Dachau” on some versions, but in the version I have, he definitely doesn’t sing this. I am not disputing the original lyrics, just trying to shed some light on his alternative lyrics. His anunciation is so clear there is no mistaking the fact that he is singing “Labau” or “La Baule.”
As I said, just trying to shed some light.
