Here we have a video of Karl Hartwich sitting in with Malek's Fishermen, doing an energetic version of the Schneider Polka. I bought an arrangement of this on E-Bay (along with a few others) and we're playing it in the Blow Musik! band. I'm trying to play it on concertina. I'm no Karl Hartwich!
Schneiden: to cut. Schneider: tailor.
