 Hammerstein wrote that Molnár 's advice , to combine two scenes into one , was key to pulling together the second act and represented " a more radical departure from the original than any change we had made " . A reprise of " If I Loved You " was added in the second act , which Rodgers felt needed more music . Three weeks of tryouts in Boston followed the brief New Haven run , and the audience there gave the musical a warm reception . An even shorter version of the ballet was presented the final two weeks in Boston , but on the final night there , de Mille expanded it back to forty minutes , and it brought the house down , causing both Rodgers and Hammerstein to embrace her .
