Because I had mentioned Rasta Thomas' Apollo at the Symphony Space "Wall to Wall Balanchine" in 2004, I googled references to that performance and came up with this interesting paragraph by Susan Reiter (emphasis mine):
'Wall to Wall George Balanchine' marks the centenary of the great choreographer.

The final, three-hour segment was dominated by performances -- necessarily to taped music since Symphony Space, a converted movie theater, has no orchestra pit. Dance Theatre of Harlem gave the New York premiere of its "Apollo," staged by Eve Lawson and coached by D'Amboise, who restored details he knew from the 1950s that have fallen away over the years. Rasta Thomas, as the still-unformed young god, faultlessly stumbled on a step that he would later, as the more mature Apollo, execute nobly.
Is the "stumble" is in the choreography?
