In 2012, a group of students made a video of a performance of Ozzy Osbourne's "Crazy Train" on various percussion instruments. At the time, the footage reached Madman himself, who donated $ 10,000 to the institution where the boys studied music, the Lousville Leopard Percussionists. Six years later, kids of the same Leopard emerged again into the life of Ozzy Osbourne - this time in person. During a recent episode of the reality show "Ozzy and Jack's World Detour", where Ozzy and his son Jack visit places of historical importance in the United States, the young musicians made a surprise appearance and played "Crazy Train" for Madman, who was also with his daughter Kelly. An excerpt from the presentation before Ozzy, Jack and Kelly Osbourne can be seen in the following video player.
