The American Idol fourth-season champ's rendition of Motley Crue's "Home Sweet Home" will serve as the "farewell song" heard after each of the eighth season's Top 13 finalists is eliminated from the competition.
In addition to serenading each of the fallen Idol finalists, Underwood's version of "Home Sweet Home" will also be sold as a digital single, with a portion of its sales being donated to The Humane Society of the United States.
"I've always loved this song, and besides being very fitting for Idol, to me, the title is also very fitting with animal rescue and finding animals their own homes," Underwood said. "So we felt it was important to tie the release into an amazing animal charity like The HSUS."
Last season, American Idol second-season champion Ruben Studdard's cover of Kenny Loggins' "Celebrate Me Home" served as Idol's "farewell song." The cover represented the first time a recording was done for the sole purpose of being used as Idol's exit song.
In 2007, fifth-season Idol finalist Chris Daughtry's "Home" was tapped as the exit song for the show's sixth-season finals. "Home" went on to garner a Grammy nomination and helped make Daughtry's self-titled debut album the top-selling album of the year.
