David Lee Roth – 65

David Lee Roth was formerly the lead singer of the original Van Halen band, but he eventually chose to go solo in his singing career owing to mounting tension between himself and guitarist Eddie Van Halen. He actually became rather successful as a solo artist and ended up reuniting with the band. They have been touring ever since their reunion. Roth can be found doing several YouTube commentaries as a side job, too. Rumors surfaced about him having announced his retirement from music, creating quite a stir earlier this year!
