An avalanche of B.O. records fell last week, including the big one. Thirty-one shows brought in $22,069,502, the highest cume to date for Broadway. It breaks the previous record of $21,350,633, the tally for 33 shows during Christmas week 2002 (Dec. 23-29).

The big difference between then and now: No fewer than 10 shows clocked nine perfs for New Year’s week 2004-05. Two years ago, no shows increased their performance sked.

Paid attendance was nearly identical for the two frames. In 2002, it came to 289,221, which compares to 288,785 tickets sold last week.

The New Year’s session marked a 38.54% increase over Christmas week 2004. Receipts were up a whopping $6,139,617.

House records toppled at several theaters. Putting in a regular eight perfs, those champs included “Mamma Mia!” ($1,130,026) at the Winter Garden, “Beauty and the Beast” ($1,044,028) at the Lunt-Fontanne, “Avenue Q” ($553,077) at the Golden and “Twelve Angry Men” ($408,192) at the American Airlines.

Nine-perf skeds for “Fiddler on the Roof” ($1,145,912), “Hairspray” ($1,095,873), “Movin’ Out” ($1,003,096) and “Rent” ($683,165) helped to set records at, respectively, the Minskoff, Neil Simon, Richard Rodgers and Nederlander.

Doing nine or not, 11 productions sold out, including “Pacific Overtures” ($383,016 for nine perfs) in the No. 27 slot on the B.O. chart.

Such nonholiday fare as bloodletting and suicide saw remarkable rebounds: “Dracula” ($462,006) and ” ‘Night Mother” ($185,949) were up 131% and 104.4%, respectively, in their final weeks. Also saying goodbye were “42nd Street” ($1,128,582), “Bombay Dreams” ($912,089), “Mario Cantone: Laugh Whore” ($264,181) and “Golda’s Balcony” ($217,744).

Only one show among the top 10 did not break $1 million. Up $121,674 on an eight-perf sked, “The Phantom of the Opera” ($976,818) came close to its top-grossing session ever: $1,006,188 during Jan. 1-7, 2001.

Best ‘Sundays’ ever

The crowded $1 million club knocked Billy Crystal out of the top 10, even though “700 Sundays” ($815,786 for only seven perfs) saw its best week to date.

Under the top 10, there were amazing increases in receipts. Coasting along on its regular eight-perf sked, “Wonderful Town” ($772,385) rose $331,351. “La Cage aux Folles” ($880,456) jumped a similar $340,220 with the big benefit of going from seven to nine perfs.

Less dramatic six-figure increases pumped the box office at “Chicago” ($734,433), “Dame Edna: Back With a Vengeance” ($466,781), “Democracy” ($462,857 for nine), “Brooklyn” ($435,175), “The Rivals” ($339,219), “Gem of the Ocean” ($311,520) and “Whoopi” ($279,222), plus previewing “Little Women” ($643,649 for nine) and “Good Vibrations” ($515,545 for nine).
