Ah ! An old mate, Stienar Offsdal of mine plays best flute and whistles in that group. They ahve won the Norwegian Spelmans prize At least once.
When I first met stienar he played in a group in '68 called the, "young Norwegians". He's over 50 now.

English phonetic pronunciation is "Booking a bruiser" ie booking a boxer.

Translation is "The bucking goat". And I mean bucking not f**king. Or do I?

Good group enjoy
