Tim McGraw, Carrie Underwood and Luke Bryan are lending their time and talents to the Muscular Dystrophy Association. The country music superstars will all participate in the annual MDA Labor Day telethon, called "MDA Show of Strength," on Sept. 2.

The show will include performances from Nashville, Hollywood and New York, as well as celebrity appearances by Khloe Kardashian Odom, Nancy O'Dell and Alison Sweeney, among others.

I don't remember the annual telethon broadcasting from Nashville before, so this will be a real treat. Just goes to show you what big hearts our country music stars have!
