Well, this is tricky.
If you're referring to Lapti Nek, the song played in the OT version of ROTJ, then anything Michael Jackson did in the mid-80s would work. If someone foreign sung it I suppose.
As for anything froma cantina, I really can't suggest anything, but there are some songs you might want to check out. You can Download all of them on Limewire, a completely free network.

It might be easier if I knew what you were planning to use the music for.
