I have something like the first Cd, but it's called "Songs and Music from Various Regions".   The track it has is "On this side of the lake a fish is drinking water"! My Polish isn't up to deciphering whether the dates are recoring or birth, though I shouldn't imagine they were making field recordings in 1866. Some of the polkas sound very like bluegrass fiddle standards. It's on Polskie Nagrania PNCD 048.

Also, does as anyone know how I can get a replacement copy of Poderti Capeliykhi's cassette. Not great but it brings back memories. I've a feeling it was only available at gigs.
