Dr. Frank-N-Furter, left, played by John Tinsley, and Brad Majors, played by Brian Sessums, sing during a “Rocky Horror Show” rehearsal. The 1970s musical with a cult following tells of a straight-laced couple who find themselves stranded outside a dark and scary mansion after their car breaks down. Performances, at the Coral Room inside The Vicksburg on Clay Street, will be at 7:30 p.m. Friday and Oct. 28; 7:30 and 10:30 p.m. Saturday and Oct. 29; and midnight Oct. 31. Tickets are $12, and no one younger than 17 will be admitted. “Rocky Horror” attire is encouraged, with a $100 prize for best-dressed at each show.
