MUMBAI: A group of young percussionists from an NGO left Black Sabbath singer Ozzy Osbourne so impressed that he donated $10,000 to the non-profit group which they belonged to. The group earned recognition more than two years after the video was originally uploaded on YouTube.

The Louisville Leopard Percussionists NGO has students aged seven to 14 from nearly 50 schools in Kentucky.

Ozbourne donated the amount after he got impressed by a cover of his song done by the young percussionists. They performed his hit single ‘Crazy Train’ and Osbourne watched their rendition on YouTube, reports aceshowbiz.com.

"Myself, my whole family and my fans all loved your rendition of 'Crazy Train'. Keep up the good work,” Osbourne said in a note to the group.

The group also attracted the attention of musician Jimmy Page with their take on Led Zeppelin's ‘Kashmir’ back in February.
