@ Coyler: no, I checked and apparently they sing that in English. To be fair, though, their speciality is more in punk rock and drinking-themed songs where they have some cracking successes such as "Kein Alkohol ist auch keine Lösung" (No alcohol is also not a solution), "Zehn Kleine Jaegermeister" (10 little Jaegermeisters) and "Eisgekuehlter Bommerlunder" (Ice-cold Bommerlunder - kind of schnapps).
