@cbssundaymorning: Shania Twain grew up dirt poor in rural Ontario and, as a child, sang country songs in bars. Throughout family hardships, divorce, and losing her voice to Lyme disease, and despite not signing a record contract until her late 20s, Twain became the top-selling female country artist of all time. She talks with Seth Doane about her biographical new album, "Little Miss Twain," in which she reflects on her life with a smile. #ShaniaTwain #Music #manifeellikeawoman #Singer #Country
