Several other people were involved in the production of the ceremony. Actor Peter Coyote, who served as announcer for the telecast, was often seen before commercial breaks live behind the stage. Musical directors Burt Bacharach, Don Was, and Rob Shrock composed a techno-pop soundtrack that substituted for a live orchestra during most of the ceremony. In addition, Bacharach rounded up musicians that included Garth Brooks, Queen Latifah, and Dionne Warwick to perform a medley of songs previously nominated for Best Original Song. Choreographer Kenny Ortega supervised the "Blame Canada" musical number.
