Kaspar got the song from an 80's band from Germany (?, could be russia) as he supplies all the music for their warmups and in the locker room. He found and it and said it sounded like they were saying prucha and thought it fit well. SO they started playing it when he scores. The first game they played it was against the Devils, but they havent sice because of the injury.
There was a thread about this song somewhere, search for it and im sure someone mentions the name of it
lyrics are in german. these guys were pretty famous here in germany a couple of decades ago. fortunately, i´m too young to have witnessed them, though. they won a chanson contest with this song i believe. the lyrics gotta be some of the crappiest EVER. if any german rangers fan hears this at the garden you should see him run away in shame.
