Walter Kerr of the "Herald Tribune" glowingly described the opening scene of the musical: "It's the beat that does it. The overture of "The Music Man" drives off with a couple of good, shrill whistles and a heave-ho blast from half the brass in the pit, with the heartier trombonists lurching to their feet in a blare of enthusiasm. The curtain sails up to disclose the most energetic engine on the Rock Island Railroad (circa 1912) hurtling across the proscenium with real smoke pouring out of its smokestack and real steam rolling along the rails". Kerr called Preston "indefatigable: he's got zest and gusto and a great big grin for another slam-bang march tune". Robert Coleman of the "New York Daily Mirror" wrote that the producer "made a 10-strike in landing Robert Preston for the title role", stating that Preston "paces the piece dynamically, acts ingratiatingly, sings as if he'd been doing it all his life, and offers steps that would score on the cards of dance judges".
