LOUISVILLE, Ky. -- Ozzy Osbourne has donated $10,000 to a Kentucky children's percussion group after watching a video of the students performing Osbourne's signature hit, "Crazy Train."

The Courier-Journal reports the rock star saw a YouTube video of the Louisville Leopard Percussionists, a group comprised of more than 60 students, aged 7-14.

The group is a community non-profit organization funded by donations, performance revenue and album sales. The students come from 48 schools in the Louisville area and practice after school.

Founder Diane Downs uses a modular approach, teaching each student a specific part of a song.

The group has performed with My Morning Jacket, Dave Samuels, Louie Bellson and Ruben Alvarez.
