The producers gave Platt a platform to perform his song even though he was more than three decades too old to qualify for the show. But they knew he was comedy gold.</p><p>On a more serious note, he was part of the civil rights movement, too. I got him on the phone at about noon today. He was rather difficult to understand at times but I cobbled together the best that I could his reactions to his song and how “Idol” portrayed him.</p><p>He was inspired to create the song three years ago when he saw a guy walking down a downtown Atlanta street with a baby in his arm and his pants slipping below his hips. “He had his underwear showing,” Platt recalled. The song came to him spontaneously. He started chanting the chorus to “Pants on the Ground.”</p>
