Underwood track for 'Idol' farewell song

Carrie Underwood's cover of Motley Crue's 'Home Sweet Home' will be used as the farewell track on this year's American Idol.

The track was especially recorded for the show by the fourth season champion and will be available for download from March 16. It will first appear on Idol this Wednesday, reports People.

Part of the money raised by the track will go towards the animal welfare group 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," said Underwood.

Previous goodbye songs included Daughtry's 'Home', Ruben Studdard's 'Celebrate Me Home' and Daniel Powter's 'Bad Day'.
