It's bloody hilarious though. I don't think G&S would have objected to adapting for new audiences..after all, their jokes worked for their audiences during their time. It's all relative really. This is obviously a more extreme adaptation with music being changed, but in it's own way I think it really works. But that's just my opinion.
They didn't really portray Pooh Bah's personality well here. He's supposed to act stuck up and be reluctant to spend time around the girls. He's not some buff womanizer!!
