When Jackman arrived, Harris claimed that Jackman must be jealous. The former host responded by saying that he only plays to "big rooms," referring to the intimate setting of the Beacon Theatre. When the argument became heated, the two fight the only way theatre folk can—in song.
Among the songs in the “Dueling Duet” were “Anything You Can Do," from Annie Get Your Gun; “A Boy Like That / I Have A Love,” from West Side Story; “Make 'Em Laugh,” from Singin' In the Rain; “I Hope I Get It,” from A Chorus Line; “Don’t Rain on My Parade,” from Funny Girl, “You’re the Top,” from Anything Goes; and “Let Me Entertain You,” from Gypsy.
