When the musical “Hello, Dolly!” premiered in 1964, it became a classic right out of the gate. Written by Jerry Herman and Michael Stewart, the original production won 10 Tony Awards and made a star out of Carol Channing, who played busybody matchmaker Dolly Levi. Its popularity even extended to Hollywood and mainstream radio: It was adapted into a successful, Oscar-winning film starring Barbra Streisand in 1969, and a version of its title song performed by Louis Armstrong overtook the Fab Four on the Billboard charts at the height of Beatlemania.
