When country singer Billy Gilman asked his pals for help in recording "The Choice," a song benefiting Soles4Souls, Vince Gill didn't hesitate. "It was a great experience to be a part of someone else's passion," says Vince. "And as far as Billy goes, I was a fan of his talent when he first turned up and all these years later it hasn't changed."

Vince was quickly joined by his wife, Amy Grant, and country stars Keith Urban, Reba McEntire, Alan Jackson and Josh Turner, who pulled on their boots and happily stepped up to the mic to add their voices to the song.

Soles4Soles, a Nashville-based charity, collects new and used shoes and distributes them to people in need. As a result of Billy's project and fans enthusiastically downloading "The Choice," 30,000 people around the world have been provided shoes. "The trucks are just now starting to leave the warehouse and we are beginning to see the positive effect that this song is having," says Billy. "Thousands of people now have a much higher self-esteem—they are now less likely to catch a disease, and more likely to land a job."

Also lending their voices to the project are Rodney Atkins, Kellie Pickler, Craig Morgan, Kenny Rogers, LeAnn Rimes, Steve Holy, Wynonna Judd, Amy Grant, Montgomery Gentry, Diamond Rio, Richie McDonald, Ronnie Milsap and Randy Travis, making it the largest collection of country stars singing on one song in the history of country music.

If you'd like to be a part of history and donate a pair of shoes, you can download "The Choice" on iTunes now.
