According to the Dragon Ball Wiki, this was sang by the Japanese singer (Kazuya Yoshii) of Cho-Zets Dynamic but this is actually in English rather than the gibberish Engrish song aired at launch with FUNi Super dubbed episodes. :) Not entirely sure it's Kazuya Yoshii, though.
P.S. This wasn't originally a release by EXIL3 but I extracted the opening as is so giving credit to him.
