Dave and Toni Arthur (I think) adapted the Hungarian ballad "Féher Anna" to "Laszlo Feher stole a stallion" - in a remarkably short time her name has got garbled into an American song about someone called "Anathea". Their tune is not the usual Hungarian one, though it does have a Hungarian sound to it.

A lot of the real magic in songs is in the text setting. Hungarian has fairly similar prosody to English, but even for that there are hardly any singable translations that preserve the tune (a choral setting by Kodaly of "Molnár Anna" translated as "Annie Miller" sort of works). For languages which have very different accentuation, like Gaelic and Turkish, it just doesn't happen.
