Madonna is in the middle of her somewhat controversial "MDNA" tour, (which includes flashing her rear in Rome and flashing her breast in Istanbul) and it's set to hit the Twin Cities November 3rd.  As a matter of fact, the Material Girl was so popular they added a second show on November 4th.  If there was any time to see Madonna--it sound like this would be it.  What goes into a production of that size for a woman like Madonna?  Well, the LA Times has done the research to break down the tour by the numbers.

Here's a breakdown of Madonna's MDNA show by the numbers:

21,000,000 fans are expected to have seen the show by the time it wraps in South America.

72,000 fans saw Madonna's sold-out show in Quebec, the largest attendance of the entire tour.

16,630 miles of road were traveled during the U.S. leg alone.

700 wardrobe pieces are required for all the performers onstage.

410 bottles of aspirin have been used, so far, by the 130-person crew.

374 is the weight, in tons, of Madonna's massive stage.

116 minutes of approximate stage time for the Material Girl, unless she adds "Holiday" to the night's set list.

90 speakers are hung onstage.

89 shows in total in 28 different countries -- 18 of those stops were in cities where Madonna had never performed.

29 trucks carry the tour's production (36 will be required for the South American leg).

24 guitars are used by Madonna and her band each night.

16 different salad dressings at required by the crew for nightly craft services.

15 buses to take the show from city to city.

9 drummers soar in the air during "Express Yourself," with another 9 on the floor.
