Officially kicking off its tour, which will stop at DTE Energy Theatre in Clarkson on Sept. 4, Van Halen rocked "Running With The Devil" on ABC's Jimmy Kimmel Live on Monday night.

And it appears that Eddie Van Halen is already making faces at David Lee Roth.

Highlights include Roth wearing a jean tuxedo while struggling to hit some of the notes; Eddie's looking in the prime of health; and Alex Van Halen is having way too many drums for a one-off appearance.

By the way, Roth's wearing a bandage on his nose, because he whacked himself in the face with the microphone minutes before air during a non-live performance of "Panama."

I'm not really sure when it happened, but you can see Diamond Dave getting medical attention at around the three-minute mark.
