Sidney provides the commentary on the DVD, and he tells us that he wanted “a train song.” Warren and Mercer gave him much more than that, for “On the Atchison, Topeka and the Santa Fe” is really an “entire town song.” It starts in the saloon—an important location, as it will be at war with the restaurant the Harvey girls wait table in—then moves to the train’s passengers, engineers, and conductor as it pulls in and the locals look everyone over, especially the newly mustered Harveys themselves. Warren’s music has imitated the train’s chugging locomotion, but now comes a trio section not by Warren and Mercer (at “Hey there, did you ever see such pearly femininity … ”), and the girls give us some individual backstories—one claims to have been the Lillian Russell of a small town in Kansas, and principals Ray Bolger and Virginia O’Brien each get a solo, too. The number is not only thus detailed as a composition but gets the ultimate MGM treatment on a gigantic set with intricate interaction among the many soloists, choristers, and extras. But now it’s Garland’s turn to enter the number, disembark, and mix in with the crowd. According to Sidney, Garland executed everything perfectly on the first try—and it was all done in virtually a single shot. Fred Astaire would have insisted on rehearsing it for a week, but Garland was a natural. Once she understood the spirit of a number, the physics of it simply fell into place for her.

And Angela Lansbury, queen of the plot’s rowdy element, does have a floor number, dressed in malevolent black and shocking pink topped by a matching Hippodrome hat. But every other number is a story number—“The Train Must Be Fed” (as the Harveys learn the art of waitressing); “It’s a Great Big World” for anxious Harveys Garland, O’Brien, and a dubbed Cyd Charisse; O’Brien’s comic lament, “The Wild, Wild West,” a forging song at Ray Bolger’s blacksmith shop; “Swing Your Partner Round and Round” at a social. Marjorie Main cues it up, telling one and all that this new dance is “all the rage way
