In an effort to ecourage Broadway and Off-Broadway theatre going in the wake of the Sept. 11 terrorist attacks, the League of American Theatres and Producers devised a TV and media campagn that would include every member of every Broadway show singing "New York, New York" in the middle of Times Square. Valerie Harper, Lea Delaria and Dick Cavett (The Rocky Horror Show) and musical theatre legend Patti LuPone were among those singing for the TV commercial's soundtrack Sept. 25. The commercial will be filmed Sept. 28 in Times Square. Radio commercials featuring the voice of The Producers stars Nathan Lane and Broderick, and a television spot in which every actor in every show on Broadway would stand in the middle of Times Square and sing "New York, New York" are a part of the advertising campaign was devised by Nancy Coyne and Drew Hodges, two old hands at selling theatre, reported the Times. One of the first ads centered on the famous "I Love New York" slogan, which places a heart in place of the word "love," but now reading "I Love New York Theater."
