The country singer looks back at her song choice and the judges' reactions from her 2004 audition in St. Louis, Missouri.

Like so many other country artists, Underwood has graced the iconic Saturday Night Live stage. Just two years after winning American Idol, the singer was the musical guest on the show on March 24, 2007. After being introduced by Peyton Manning, she performed her songs " Before He Cheats " and " Wasted ."

But this year will feel a little different with Katy Perry stepping down. Perry has served as a judge since the series was rebooted in Season 16. After Season 22, Perry turned her attention to releasing music and touring.
