TODAY IN THEATRE HISTORY: In 1975, after a smash run at The Public Theater in New York City, the Marvin Hamlisch-Edward Kleban musical A Chorus Line makes the move uptown to Broadway’s Shubert Theatre. The Michael Bennett-helmed show, including such songs as “What I Did for Love” and “One,” features Donna McKechnie, Kelly Bishop and Robert LuPone. A Chorus Line will truly prove to be, as its lyrics say, “one singular sensation,” racking up 6,137 performances to become Broadway’s longest running show up to that time. (In June 1997, Cats will break that record.)
