NEW YORK — Broadway grosses were off a smidgen for the last week of the season (May 19-26). Grosses for the 29 shows on the boards were down 3.8% to $15,133,099. Attendance of 238,347 was off by a similar 3.4%.The overall decline was largely due to the closing last week of “Les Miserables.” Most shows actually saw B.O. leaps, as bad weather over the Memorial Day weekend sent audiences into theaters. Tourist tuners “The Phantom of the Opera,” “Beauty and the Beast” and “Aida” led the gainers. A loss of $38,906 at “Long Day’s Journey Into Night” was primarily due to tickets returned when Vanessa Redgrave missed perfs following the death of her mother, Rachel Kempson. Still, the show played to 89% capacity for the week and grossed a healthy $553,727, far outdistancing any other play. The 20 musicals grossed $12,579,560 for 83.1% of the Broadway total, with attendance of 192,112 at 87.3% of capacity. The nine plays grossed $2,553,539 for 16.9% of the Broadway total, with attendance of 46,235 repping 72.7% of capacity. Average ticket prices were $65.48 for musicals, $55.23 for plays and $63.49 for all shows.
