The band shut down Hollywood Boulevard on Monday to perform an 8-song greatest hits set for the late night program as they launched their latest album, "Tokyo Dome Live In Concert."

During the band's opening number, "Panama", frontman David Lee Roth injured himself when his martial arts stick/baton cut his nose, forcing the singer to stop the event while he was treated. The injury was originally believed to have been caused when Roth bumped his nose on a microphone.
