STARS ANNOUNCED FOR MDA TELETHON THIS LABOR DAY WEEKEND ON ABC

Ryan Seacrest, Backstreet Boys, Darius Rucker, Paula Abdul, Enrique Iglesias, Matthew Morrison and Austin Mahone Among Those to Appear on Two-Hour Broadcast

The Muscular Dystrophy Association has announced a star-studded celebrity lineup that will appear on its 48th annual telethon this Labor Day weekend, SUNDAY, SEPTEMBER 1 (9:00-11:00 p.m., ET) on the ABC Television Network. Called "The MDA Show of Strength," the telethon will feature: Ryan Seacrest, Backstreet Boys, country stars Darius Rucker and Lee Ann Womack, "Glee" stars Matthew Morrison and Jessica Sanchez, Enrique Iglesias, Paula Abdul, teenage pop sensation Austin Mahone, hip-hop dance crew Jabbawockeez, Kenny Loggins with the Blue Sky Riders, American blues rock band Vintage Trouble and Universal recording artist and star from the "The Voice" Chris Mann.

Additional presenters for the 2013 show include: ABC's Dr. Richard Besser, "Dancing with the Stars" Season 11 contestant and "Brady Bunch" mom Florence Henderson, Emmy Award-winning journalist Jann Carl, Olympic gold medal gymnasts Nadia Comaneci and Bart Conner, and "No Doubt" drummer Adrian Young and his son, Mason Young.

This year's lineup will deliver one-of-a-kind show performances as they join celebrity presenters to engage viewers with powerful "stories of strength" and moving calls-to-action to help families affected by muscle diseases.

"The MDA telethon is an American tradition, powered by celebrities, national sponsors and, most of all, generous individuals who watch and donate," said MDA President and CEO Steven M. Derks. "This year we'll tell a powerful story of the progress we're making and breaking developments underway in the fight against muscle disease. We want America to get a glimpse of the hope we have that new lifesaving treatments are on the horizon as told through the eyes of courageous people fighting various neuromuscular diseases. On behalf of the tens of thousands of families we serve, MDA is remarkably hopeful and enormously grateful to all our supporters who make this progress possible. We think this year's show will be our best ever, truly a moving and entertaining two-hour experience."

R.A. (RAC) Clark, longtime executive producer of the Academy of Country Music Awards, will return this year as MDA telethon executive producer. The week before the broadcast, MDA is planning kickoff parties in communities in every state in the nation to rally interest and engage new supporters.

A public service campaign is being launched this week to promote the show.

While the telethon has consistently enjoyed robust support from some of the biggest celebrities in show business, MDA says the real stars on the broadcast are the individuals and families served by MDA, including six families who will tell their stories of survival and hope during the 2013 broadcast.

The complete list of profiles includes:

· Cooper Somers, a vivacious Houston toddler battling spinal muscular atrophy (SMA), who tragically lost his dad in a car accident in the past year

· Reagan Imhoff, a lovable and driven 8-year-old from suburban Milwaukee, also diagnosed as having SMA, with big dreams of becoming a professional dancer

· 11-year-old identical twins Nolan and Jack Willis from Fayetteville, NY, who have Duchenne muscular dystrophy and are taking part in a promising clinical trial

· India Peters, 21, an adventurous young lady from Oxon Hill, M.D., learning to transition into adulthood while dealing with facioscapulohumeral muscular dystrophy (FSHD);

· Juan Morales, 28, from Pembroke Pines, FL, who is fighting SMA and has a master's degree in psychology from Florida International University; and

MDA Telethon History

The MDA telethon is one of America's longest-standing and beloved fundraising and entertainment events. For 48 years, funds raised by MDA telethons also have contributed to the organization's worldwide research program. Today, through current clinical trials, there is growing excitement that new lifesaving treatments and discoveries are on the horizon for many of the disorders MDA is dedicated to defeating, including Duchenne muscular dystrophy (DMD), spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS).

MDA's first Labor Day weekend telethon was broadcast in 1966 on a single New York station and has become the most successful fundraising event in the history of television. The show, with Jerry Lewis as its iconic host through 2010, and with help from a legion of top celebrities and entertainers, has raised millions each year to provide life-enhancing support and services for the families MDA serves.

In addition to funds contributed by the public, substantial support also comes from MDA's family of national sponsors, whose work throughout the year on behalf of MDA will be recognized on the telethon. Among the sponsors: International Association of Fire Fighters, CITGO Petroleum Corp., Safeway, Lowe's, Harley-Davidson, Jiffy Lube International, National Association of Letter Carriers, 7-Eleven, 7UP, Acosta and Burger King.
