When the Louisville Leopard Percussionists recorded this video of themselves performing Led Zeppelin hits, it became a viral hit with Jimmy Page even giving them a shout out on his Facebook page.

But the Leopards are back in the news for their equally stellar version of Ozzy Osbourne’s “Crazy Train,” and Ozzy Osbourne is doing more than just giving them props.

The Black Sabbath singer and metal icon has actually donated $10,000 to the non-profit after-school group.

Good on you, Ozzy!
