The long July 4 weekend may have seen hot bodies seeking refuge in air-conditioned seats, but they weren’t cooling down in Broadway theaters. The 28 shows were off 13% from the previous week. An impressive 21 of them were down more than $50K; indeed, 12 shows came up more than $100K short of the week before: Beautiful, at the Roundabout’s Stephen Sondheim (-$193K); Wicked, at the Nederlander’s Gershwin (-$183K); Something Rotten!
