An East european Gypsy group did this at Holstein's; can't remember their name, unfortunately - they were very adamant that it was an old Gypsy song and sort of dared ?McCartney to get after them -- thewy sang it in their native tongue but I had the clear impression the lyrics were the same. The tune was identical, which I can believe. I first heard it when I was a student in Germany in (mumble mumble) at a retreat, being played for a folk dance, so I believe every word.
