During the 1991 Gulf War, business on Broadway faltered as people stayed home. That hasn’t happened so far with the Iraq war. Last week “business climbed primarily for musicals, with two of the most popular, ‘Hairspray’ and ‘The Lion King,’ selling out and grossing over $1 million each. There were sturdy ticket sales for such shows as ‘The Producers,’ ‘Mamma Mia!’ and ‘Chicago’. Although overall ticket sales were off from a year ago, $12.9 million compared to $14.2 million in 2002, there were more shows playing last year – 31 shows compared to 27 productions last week.”
