An MTV crew will be at Petrus tonight filming costumed revelers and other grateful undead at a Halloween party sponsored by WAPW-FM (Power 99). Featured guests include recording artists Belinda Carlisle, the Beastie Boys and DJ Jazzy Jeff and the Fresh Prince. Gloria Estefan of Miami Sound Machine is also rumored to be making an appearance. The party, after Power 99's "Terror Train" trip to Stone Mountain aboard the New Georgia Railroad for contest winners, is open to the public for the modest cover charge of $8.
