On Tuesday night's episode of America's Got Talent, 12-year-old Evie Clair performed Louis Armstrong's classic "What a Wonderful World" in honor of her late father, who died two weeks ago from late-stage colon cancer. Clair, who used to sing to her dad to comfort him during his battle with the disease, also explained why she was staying in the competition after her painful loss. "My dad taught me, after I started something, to always finish it," she recalled. "That's why I'm fighting to the end, just like he did." Clair fought back tears as the audience and judges gave her a standing ovation for her strength and touching performance. Mel B, who recently lost her own father, told the girl, "I know your dad's up there, looking down on you, and he must be so, so proud."
