Lead singer of Van Halen, David Lee Roth, was staying in a Las Vegas hotel when he overheard a bachelor party blasting some Van Halen music. So he decided to drop by.
Unfortunately none of the party-goers recognised his name or face, with it all caught on camera.
"We heard some Van Halen here and my name's David Lee Roth and I'm right across the hallway. The fellas here were coming down the hallway and they said, 'Shit, we heard some Van Halen,' And I said, 'Nah, shit!’", Roth says in the clip, met by bemused looks from the bachelor party attendees.
