Ozzy Osbourne and his band Black Sabbath have long been considered one of the first heavy metal bands, with Ozzy himself being dubbed the "Prince Of Darkness".
But he'd gone in a different direction after the band split? Musician and composer Andy Rehfeldt decided to play around with some old footage and set Ozzy's vocals on "Over The Mountain" to a ska beat. The results are really, really odd.
Andy, who goes by the YouTube moniker of Wilton Turdley, is also behind the polka version of Fetty Wap's "Trap Queen" and the heavy metal version of Katy Perry's "California Gurls".
