Hmm, okay then. Well they should have made that more obvious with like glasses and windows shattering when they started to sing, and maybe all those extras prancing about in flippers could have put in ear-plugs instead.
They could have afforded some comedy special effects like that with the money they saved in not having to employ any scriptwriters.
At the end I was thinking Bjorn and Benny would be spinning in their graves (if they were dead) and then I saw THEY ARE NAMED ON THE CREDITS AS BEING INVOLVED IN THE PRODUCTION!
It's a shame, they must be really hard-up.
