Dolly Parton’s mom used to sing melodies as a child, including “Bury Me Beneath The Willow," but she didn’t expect to bring Stephen Colbert to tears. The legendary country singer made an appearance on “The Late Show with Stephen Colbert” to talk about her latest book “Songteller: My Life in Lyrics" and her latest holiday album “A Holly Dolly Christmas." “My mama was a good singer, she used to sing songs that were sad, and sometimes pitiful,” she told Colbert. She proceeded to sing a piece of “Bury Me Beneath the Willow”, drawing Colbert in tears by her singing. “You know sometimes there’s nothing happier than a cry?” he said while quickly wiping tears off his eyes during the show.
