#InTheLab With Arthur Kade was on the red carpet of the premiere of HBO’s “Moms Mabley” directed by Whoopi Goldberg at the Apollo Theater. We chatted with Whoopi, as well as Kathy Griffin (She was performing at Carnegie Hall the next night), Dick Cavett, Rain Pryor, Margot Bingham (Daughter from HBO’s Boardwalk Empire) and more.
