Trace Adkins is planning a very special performance for Sunday's ACM Awards. He'll sing 'Til the Last Shot's Fired,' backed by the the West Point Glee Club choir. The performance is being presented in support of the Wounded Warrior Project (WWP), the charity selected this year by the ACM's charitable fund, Lifting Lives. The song will be available to download at iTunes, with all profits benefiting the WWP, which provides support to troops wounded in combat. The 60-voice choir, first organized in 1903, also recorded the song with Adkins for his latest album, 'X.'

Also scheduled to perform at the ACM Awards are Lady Antebellum, Kenny Chesney, Miley Cyrus, Rascal Flatts, Jamey Johnson, Toby Keith, Miranda Lambert, Reba McEntire, Tim McGraw, Heidi Newfield, John Rich, George Strait, Sugarland, Taylor Swift, Carrie Underwood, Keith Urban and Lee Ann Womack. The 44th annual ACM Awards air this Sunday at 8 PM ET on CBS.
