4-year-old leukemia patient gets standing ovation at Fenway

A 4-year-old singer brought the crowd to its feet at a recent Red Sox game at Fenway Park in Boston.

Darla Holloway, who is suffering from acute lymphoblastic leukemia, sang "God Bless America" during the seventh-inning stretch Tuesday night. She is currently undergoing chemotherapy treatments, but told Boston sports-talk show "Mut & Merloni" that she was practicing every day for her Fenway Park debut.

Before the game, Darla was also part of the Jimmy Fund chorus that sang the National Anthem.
