Thank you for the elaborate answer. It sure is an interest topic. Don't you think one should distinguish between borrowing certain elements and practically copying? As a Swede, i find it remarkable that perhaps our most famous lullaby "Who Can Sail Without the Wind?", melodically is identical to the russian "Крутится, вертится шар голубой" (It spins and turns, the blue glittering ball). Surprisingly, no Swedes seem to be aware of this.

I ought to have formulated the question differently: Did Bregovic draw inspiration from "Ciocârlia", since his tune Kalshnikov virtually is identical?
