Connick has done this plenty. Google his name along with "national anthem," and a handful of videos from past performances come up, dating as far back as the 1992 Super Bowl. While not a huge baseball fan, Connick loves the atmosphere and the excitement that comes along with jewel sporting events.
"I like being around the energy, especially in these high-level games like the World Series and Super Bowl," the singer said. "It's nice."
Without a Major League team in New Orleans, Connick's exposure to baseball was limited. He lives somewhat vicariously through his dad, who holds a strong allegiance to the Red Sox, but beyond that, he's a casual observer.
Still, Connick loves being at the ballpark.
"I like singing at different venues," he said. "It's always a lot of fun."
The pregame ceremony also included the ceremonial first pitch, thrown by a legend in these parts -- Hall of Famer Ozzie Smith, whose game-winning homer in Game 5 of the National League Championship Series is still one of the Cardinals' most memorable postseason moments.
Smith has made several appearances in the pregame ceremonies throughout October, having joined many former teammates and fellow Hall of Famers on the field as part of the pageantry that surrounds postseason play.
Scheduled to perform "God Bless America" in the middle of the seventh inning was Tech. Sgt. Angie Johnson of with the Missouri Air National Guard.
Additionally, Bank of America, the official bank of Major League Baseball, provided American flags for fans at each Busch Stadium entrance, asking those in attendance to wave the flag during "God Bless America" as an expression of thanks to our troops.
Bank of America will donate $1 on behalf of each participating fan to Welcome Back Veterans and the Wounded Warrior Project in an effort to reach a total donation of $1 million, which will go toward helping service members and veterans succeed here at home.
Bank of America's "Express Your Thanks" initiative, which relaunched on Memorial Day 2013, aims to help support members of the military and veterans across the country by donating $1 for each expression of thanks.
