"Xanadu" star Kerry Butler talks about her childhood performances of Olivia Newton-John songs and how they've informed her Broadway role as Kira, as well as the ins and outs of roller-skating on stage; her deep affection for the musical "Blood Brothers" and her experience in the Broadway production; her separate appearances in two somewhat blood-thirsty musicals, "Bat Boy" and "Little Shop Of Horrors"; why she took the originally underdeveloped role of Penny in the original "Hairspray"; and which of her roles fans most frequently mention when she meets them at the stage door. Original air date – September 7, 2007.
