Broadway got a holiday boost last week, with the late-spring uptick feeling some extra lift from Memorial Day weekend.

Most productions on the boards posted gains, although few increases proved remarkable. Large-scale tourist-magnets benefited most from the weekend traffic, with “Shrek the Musical (up $135,000 to $770,039) seeing the heftiest surge of the frame.

“The Phantom of the Opera” ($810,280), “Mary Poppins” ($778,623) and “The Little Mermaid” ($775,764) also stepped up by more than $100,000 each.

Total cume of the Rialto rose about $950,000 to $20.5 million for 34 shows on the boards. Attendance climbed by about 10,000 to 271,392, putting overall aud capacity at 84%.

In its final week, struggling play revival “Desire Under the Elms” ($346,570) reported one of the larger gains of the sesh, with biz spurred by last-minute ticketbuyers. But in an indicator of how tough it is to attract theatergoers in a crowded play season, two Tony-nommed revivals, “Mary Stuart” ($320,683) and “The Norman Conquests” ($304,815), were among the shows that saw receipts slip last week.

Well-reviewed new play contender “Reasons to Be Pretty” ($176,152) did rise by more than $35,000, but still only played to 50% capacity. “Irena’s Vow” ($177,701), left out of the Tony race, was down.

Among the spring musical entries, “9 to 5” ($805,908) didn’t rise by much but nonetheless broke the $800,000 mark for the first time, while both “Rock of Ages” ($450,676) and “Next to Normal” ($337,306) continued to gather momentum.

Along with “Desire,” Jane Fonda starrer “33 Variations” ended its limited engagement of middling sales last week, pulling in $236,250 for a five-perf frame.
