“We’re delighted to have Bradley Walker back on our show,” said Gerald C. Weinberg, MDA president & CEO, and Telethon executive producer. “His talent is incredible. Bradley’s life is filled with challenge, but he perseveres in his hope and confidence that MDA will find a cure for his disease. His story, and his performance, will inspire Telethon viewers.”

In 2006, Walker released his debut album, “Highway of Dreams” (Rounder Records). In 2007, the International Bluegrass Music Association named him Male Vocalist of the Year. Bluegrass Unlimited magazine hailed him as the "next great voice of bluegrass music."

Walker made his first appearance on the Telethon in 1989 with the Oak Ridge Boys. He’s received standing ovations for his performances on the Grand Ole Opry, and has frequently appeared with bluegrass headliner groups including The Lonesome River Band and Lost Horizon.
