The Dixie Chicks are scheduled to perform a new song called "I Believe In Love" on Friday's four-network simulcast "America: A Tribute to Heroes."

The Chicks issued a statement saying: "We are participating in this event because, like everyone else, we want and need to do whatever we can to help. It's easy and important to send money, but something inside just makes you want to do more. This tribute telethon is a great opportunity to help raise millions of dollars, say thanks to the men and women who put their lives on the line for us and to be a part of this amazing coming together of our nation."
