(Gus Ruelas | AP file photo) In this Oct. 18, 2007, photo, Emily Robison, left, and Martie Maguire, right, adjust Natalie Maines' hair as the Dixie Chicks perform at the new Nokia Theatre in Los Angeles. The Grammy-winning country group have dropped the word dixie from their name and are now going by The Chicks. The move follows a decision by country group Lady Antebellum to change to Lady A after acknowledging the word's association to slavery.
