the KlezmerShack

As is usually the case with a non-musician, I can place this tune, but can't name it. Can anyone help?

I'm an Israeli composer and pianist. I used to go to NEC, but now I'm doing a scholarship year in Berlin. I'm contacting you because I have a klezmer band here, and we're playing some tunes, some of which we don't know the composer and name of tune. I attached here the mp3 with the tune. If you recognize it, can you tell me what it is?

We are putting together a demo CD with a few tunes and would really like to put correct information.

Thanks very much in advance,
