Carrie Underwood will be featured Wednesday (April 25) on American Idol in a video segment taped in April during a trip to Johannesburg, South Africa. The journey was organized as part of American Idol’s “Idol Gives Back” charity special. During her two-day visit, Underwood and three members of her band performed at schools, orphanages, hospices and health care centers. Underwood recorded an acoustic version of the Pretenders’ “I’ll Stand By You” to be used as the musical background for the TV show. Underwood is the season four winner of American Idol.
