David Lee Roth Crashes Bachelor Party, No One Recognizes Him David Lee Roth is known as one of the most entertaining frontmen in rock unless you're a bunch of dudes at a recent bachelor party who had no idea who the singer was when he came knocking on their hotel door. Footage from The Roth Show shows a clueless guy opening his hotel room to the Van Halen frontman during the awkward exchange. Once the guy opens the door Diamond Dave says "The fellas here were coming down the hallway and said 'We heard some Van Halen' and I said 'Nah, s***!" which was received in uncomfortable silence by the Vegas bachelor party crowd. The internet has come hard for the bachelor party for their cluelessness. If you could have any rockstar knock at your door during a party who would you pick?
