The Kransky Sisters! Imagine a trio of spinster Munster siblings formed a girl group, picked up a tuba, a musical saw, an old casio keyboard and sundry pots & lids from the kitchen, and proceeded to do unique versions of everything from AC-DC to The Sugababes.
I've written about the Kransky Sisters before, but now they have their own home on the web. Yay! Unfortunately The Man has cut off my YouTube access here at The Big Christian Charity otherwise I'd link direct, but if you go here and scroll down to the bottom of the page there are heaps of links to their clips on YouTube.
Watch. Laugh. Be afraid a tiny bit.
