David Lee Roth was in Vegas recently and heard someone in a hotel room across from his own blaring Van Halen’s music. So, being the party lover that Roth is, he decided to see who was playing it. It turned out to be a bachelor party that Roth walked in on. The only problem was that the young men celebrating had no clue as to whom the former Van Halen frontman was. Roth asked who was playing the music, and the men seemed apologetic, thinking he was asking them to turn it down. To be fair, Diamond Dave looks dramatically different from his days on stage with Eddie and company.
