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.

Other artists participating in the three-hour telecast include Gavin DeGraw, Alanis Morissette, Paula Abdul, Hot Chelle Rae, Carole King, OneRepublic and Jesse McCartney, among others. 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. In addition, six families who have a personal connection to muscular dystrophy will share stories of strength, revealing how they have coped with such a debilitating disease.

"We couldn't be more excited about the show and the incredible talent we have lined up this year," says MDA Interim President Valerie Cwik, M.D. "MDA is in business to save and enhance lives. Our show will both entertain and urge the American public to answer the call to support critically important research and services for more than a million Americans affected by neuromuscular diseases."

"MDA Show of Strength" will air Sept. 2 at 7:00 PM ET on MDA's Love Network of more than 150 stations across the country, as well as on the MDA website. See a complete list of stations that will air the broadcast here.
