 The other aspects of the telethon, such as corporate donations, stories from those who relied on the MDA's help, and local segments, remained, though local segments were restricted to two 7- to 8-minute segments every hour.Stars featured in the first short-form version included Lady Antebellum, Martina McBride and Darius Rucker, in pre-taped segments from the Grand Ole Opry in Nashville, Tennessee, the judges of "American Idol" (Jennifer Lopez, Steven Tyler, and Randy Jackson), Celine Dion, Jon Secada, Tommy Emmanuel, Richie Sambora, Jimmy Webb, Michael Feinstein, Maureen McGovern, Jordin Sparks and Greyson Chance.The 2011 telethon was the first edition to broadcast the national segments in high definition; the broadcast of local segments in HD remained optional for the station.
