Iowa maniac came to the rescue when Jonathan Davis was hospitalized at Download festival

Korn's appearance at 2006's Download festival didn't go as planned. Shortly before the band were set to take the stage, frontman Jonathan Davis was rushed to the hospital and treated for a blood disorder, rendering him unable to perform at the U.K. mega-festival. Instead of calling off the show entirely, the rest of his nu-metal bandmates quickly scrambled to find guest musicians to fill his shoes for the set, and among the A-list crew that included Avenged Sevenfold's M. Shadows, Trivium's Matt Heafy and DevilDriver's Dez Fafara, was Slipknot frontman Corey Taylor.

The vocalist, who was at Download performing with his other band Stone Sour, joined Korn onstage for the songs "Freak on a Leash" and "Clown," and considering the last-minute nature of the set, he totally killed his parts and made the crowd go wild despite Davis' absence.
