Input: Question: How many theaters showed the 1968 horror film that inspired the zombie dance during its initial theatrical release? Passage:Three songs have been used for the reality television series So You Think You Can Dance. "Ramalama (Bang Bang)" was used for a group performance on the sixth week of the second season. Contestants wore costumes and make-up to show them as zombies in a performance combining the 1968 horror film Night of the Living Dead with Michael Jackson's 1983 music video for "Thriller". At the 59th Primetime Emmy Awards, the performance was part of a three-way tie for Outstanding Choreography with a So You Think You Can Dance performance of Céline Dion's "Calling You", choreographed by Mia Michaels, and the television special Tony Bennett: An American Classic. "Night of the Dancing Flame" was used for a couple's jazz dance in the fourth week of the following season with contestants Neil Haskell and Lauren Gottlieb. The performances were choreographed by Wade Robson. Robson also did a number to "Ruby Blue" in the fifth season of So You Think You Can Dance.
