Oh, dang. Can't link to song samples at CDNOW any more, I guess. Darn them.
Let's see if I have any luck with Amazon. Nope, not them, either. You'll recognize the tune right away from their accordion orchestra sample. Click here and then find the song yourself at the bottom half of the page.
I kind of doubted that there was a connection between your song and Von Weber's piece, LEJ - but classical composers often use folk melodies, so my idea wasn't as far-fetched as it might seem.
