Aguilera invited to sing anthem at AHL game

This post should be in the Wilkes-Blog section, but Eric P. is too busy cutting Dustin Jeffrey pictures out of Tiger Beat magazine.
The AHL's Syracuse Crunch has invited Christina Aguilera to sing the national anthem for a game.
The contents of the invitation, via NHL FanHouse:
"We witnessed your performance at yesterday's Super Bowl," the letter says, "and recognize and appreciate how difficult and intimidating it can be to sing our country's national anthem in front of a crowd of more than 102,000 and a worldwide television viewing audience of over 150,000,000.

"At this time we would like to invite you to re-perform the Anthem at our home game on Saturday, Feb. 19 against the aptly named Rochester Americans. This opportunity certainly gives you a forum to properly demonstrate just how well you can perform the anthem before an intimate crowd of 6,200 fans in the heartland of America — Syracuse, N.Y."
Don't care who you are or what you're doing, this will pump you up.
If you played roller hockey at Cecil Park between the years 1995-2003, you know every nuance of this rendition.

Makes you wanna drive through a brick wall with your S.U.V. and credit cards.
Solid Wiki read, too: Star-Spangled Banner
And why is the Star-Spangled Banner played before sporting events?
Seems like Canada had a hand in it:

It is generally accepted that its first appearance during a sporting event was the 1918 World Series. To demonstrate major league patriotism, baseball teams had the players march in formation during pre-game military drills while carrying bats on their shoulders. During the seventh-inning stretch of game one, when the band spontaneously began to play the "Star Spangled Banner," the Cubs and Red Sox players stood at attention facing the centerfield flag pole. The crowd sang along and applauded when the singing ended. 

Given this reaction in Chicago, the "Star Spangled Banner" was played during the seventh-inning stretch for the next two games. When the Series moved to Boston, the great theatrical Red Sox owner Harry Frazee pumped up the show biz: He brought in a band, and the song was played before the start of each game.

When the war ended, the song continued to be played, but only on special occasions when a band was present — such as opening day, special holidays or the World Series. On opening day in Washington, D.C., it was played before the president of the United States, and local politicians in other cities learned to participate in the events.

The "Star Spangled Banner" was finally declared the official national anthem in 1931. Even though by 1934 some ballparks had public address systems, it still was not played at every game. The coming of war in the late 1930s changed all of that. During the 1939-40 National Hockey League season, the Canadian anthem was played at games in Canadian cities as Canada was already at war. Then the practice spread to Madison Square Garden and from there it was transferred from hockey to baseball. — Some site
