Stone Sour frontman Corey Taylor joined Steel Panther (formerly Metal Skool) on stage Monday night at the Key Club in Hollywood, CA for a rendition of Judas Priests' "You've Got Another Thing Comin" with Scott Ian (Anthrax) on guitar. After a couple shots of Jack Daniels, Corey was ready for some Poison. He was joined on bass by Black Presidents and Unwritten Law bassist, Pat "PK" Kim for "Nothin' But a Good Time."
