Janet Denney Cobb, wife of Randall "Tex" Cobb, has just completed "The Lady and the Blue," a documentary film about Vernoca L. Michael, the nation's first female African-American boxing promoter, who co-owns The Legendary Blue Horizon (1314 N. Broad). Cobb and her movie partner, Alexander Calzi, shipped their 78-minute film to a handful of festivals and are awaiting results. "It's about her relationship to the last great fight club in America," Cobb told us. She sat ringside with Cobb, a former boxer and "Raising Arizona" star, at a fight-night Friday at the Blue. Eagles tight end Brent Celek was there repping his hometown/college town with a Cincinnati Reds cap and a red track jacket, taking in the bouts from a balcony seat.
