David Lee Roth (sometimes referred to as "Diamond Dave") (born October 10, 1954, Bloomington, Indiana) is an American rock vocalist, songwriter, actor, author, and former radio personality, best known as the lead singer for Van Halen. After leaving Van Halen, Roth started his own career as a solo artist. His early albums were well received, but starting in the early 1990s, subsequent releases fared successively worse as popular musical tastes changed and Roth's band underwent numerous personnel changes.
Roth has re-united with Van Halen, and the group has recently concluded a lengthy North American Tour. In 2008, an album and further worldwide touring are proposed to follow.
Several websites lis Roth as a 'famous vegetarian' but the only direct comments we can find are those below:

Well, I ran into Dave during the day. I had read somewhere where he was slagging off vegetarians who “eat birdseed.” I met him in a veggie fast food joint, and he seemed a nice guy. And he said he loved his veggie burger.
He struck me as someone who had his role down, but seemed well-grounded.
Sammy Hagar kind of freaks me out with all of his gun-toting vegetarian-hatred, and David Lee Roth was the only real Van Halen front man.
