Country music will be well represented and show its support of a good cause at the 2012 Muscular Dystrophy Association's Labor Day weekend entertainment special (formerly a "telethon") called 'MDA Show of Strength.' Carrie Underwood, Tim McGraw and Luke Bryan are all set to appear, alongside a slew of pop stars, ranging from Pitbull to Taylor Swift's partner-in-rhyme B.o.B.

The three-hour, prime time broadcast will air on Sunday, Sept. 2 at 8/7PM CT from three locations: Hollywood, Nashville and New York. It will not only include over a dozen of today's biggest and brightest names in entertainment; it will also feature "stories of strength," spotlighting families affected by muscular dystrophy and related conditions and diseases. So this special will encompass many things and is certainly worthy your while to watch, be entertained and more importantly, to learn.

The show will be broadcast over MDA's 'Love Network' of almost 150 television stations across the country and streamed from here.

"We couldn't be more excited about the show and the incredible talent we have lined up this year," said MDA Interim President Valerie Cwik, M.D., in a press release announcing the event. "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."

So tune in – both for a good cause and to be entertained by the likes of Underwood, McGraw and Bryan.
