David Lee Roth reunites with Van Halen for 'Jimmy Kimmel Live' concert

Van Halen performed classic songs and shut down Hollywood Boulevard for their performance on "Jimmy Kimmel Live" this week. It is the band's first ever televised performance with original lead singer David Lee Roth.

The band's performances of "Panama" and "Runnin' with the Devil" aired Monday night.

Roth sported a bloodied bandage during the performance after he banged his nose up on the microphone, ABC News Radio reported. The song was restarted and the backstage drama didn't make it to air. A video posted to YouTube, though, shows the rocker returning to the stage and explaining what happened.

A crowd of around 6,000 fans squeezed onto the street for the performance, Kimmel said.

The comedian of course took the opportunity to make fun of how long the band, formed in 1972, had been around.

"You know that teacher they were so hot for? She just went through menopause," Kimmel joked.

Guillermo immersed himself in the crowd of die-hard fans and the show even played a game to guess whether the fans had Van Halen tattoos.

Tickets for Van Halen's summer and fall North American tour go on sale Saturday. Their televised performance will continue Tuesday on "Jimmy Kimmel Live."
