It’s coming, it’s coming, says Queen City artistic director Lyle Benjamin of the Cincinnati premiere of August Wilson’s drama about life in a gypsy cab company. Originally scheduled to open next week, Benjamin says the show will go on but he’s also sweating out grants. Benjamin is trying to hang on to a crackerjack cast including Tony Davis and Reggie Willis for a mid-February opening. Benjamin hasn’t given up on big dreams of producing Wilson’s epic “Gem of the Ocean” this season, either.
