It was down to eight couples Wednesday night on So You Think You Can Dance? as choreographer and general friend of the show Adam Shankman joined regular judges Mary Murphy and Nigel Lythgoe. Mary said this would be the shows best year ever because at this point in past seasons they've generally had a better idea of who the front-runners are. Nigel took a moment to pay tribute to legendary dancer and actress Cyd Charisse, who died last week. He and Adam suggested that folks go rent some of her classic movies, including Singin' in the Rain, The Band Wagon, Silk Stockings and Brigadoon. Nigel called her a remarkable woman and real star of dance. Host Cat Deeley said each couple would say a bit out their partners before each dance. (thetvdb.com)
