Vince Gill will sing “I Can’t Stop Loving You” as part of a tribute to Ray Charles at the annual Capital Fourth celebration Sunday (July 4) in Washington, D.C. Gill and his wife, Amy Grant, are among the musical headliners for the annual patriotic celebration to be held on the West Lawn of the U. S. Capitol and broadcast live on PBS. Gill and Grant will also make a July 3 appearance on the Fox Network’s Fox & Friends. The Capitol Fourth concert will also feature performances by American Idol’s Clay Aiken, Bee Gees member Robin Gibb and gospel vocalist Yolanda Adams. “I Can’t Stop Loving You,” from Charles’ groundbreaking album Modern Sounds in Country and Western Music, held the No. 1 spot on Billboard’s pop charts for five weeks in 1962. The song was written by Country Music Hall of Fame member Don Gibson.
