Black Sabbath – The Polka Tulk Blues Band
There’s a LOT to unpack from that original name. First, it’s worth remembering that since Black Sabbath undeniably helped usher metal music into what it became, they thought of themselves as a blues-rock band at the very beginning, because that’s what they liked.
As for Polka Tulk? Apparently, it was a reference to the talcum powder that Ozzy’s mother used. As for the final (and legendary) name, it derives from the Mario Bava film Black Sabbath from 1963.
And they are, and always shall be The Village Idiots.
AC/DC = Anti Christ Devils Child
Have fun.
