The 2011 MDA Telethon has joined forces with the Grand Ole Opry to bring some of your favorite country stars to your television screen this Labor Day weekend. The annual broadcast is set to air Sunday, from 6:00 PM - 12:00 AM in all time zones, and will include Opry performances by Martina McBride, Lady Antebellum and Darius Rucker, who duets with a very special, 12-year-old singing partner.

Darius told  theboot.com,"I'm excited for everyone to hear and see the special duet version of 'Come Back Song' featuring Miss Abbey Umali, MDA's National Goodwill Ambassador. "Abbey has musical talents well beyond her years, and I hope her performance inspires you to support the Muscular Dystrophy Association fight progressive muscle diseases. For me, I'm just happy to help so many deserving kids like Abbey.''

The telethon has Martina thanking God for her three healthy daughters. "I am so grateful for our many blessings," says the country songbird. "My being part of the Telethon is important to me because every mother and every child deserve to share the brightest possible futures. Happily, thanks to generous public support, MDA is making real progress in the fight against muscular dystrophy. If you tune in Sunday, I know you'll be inspired to help MDA do even more.''

The non-profit organization  does  more than just  fight muscular dystrophy through research and treatment. It also helps families affected by MD and funds summer camps for kids battling the disease, among many other services.

The 2011 MDA Telethon will broadcast on  TV stations nationwide and stream worldwide on the internet at mda.org. Some of the biggest names in music are scheduled to appear, including Steven Tyler, Jennifer Lopez, Smokey Robinson, Celine Dion, Richie Sambora, Jon Secada and Billy Ray Cyrus, who will perform his new song on the telethon.
