Deborah Anne "Debby" Boone (born September 22, 1956), is an American singer, author, and actress. She is best known for her 1977 hit, "You Light Up My Life", which spent ten weeks at No. 1 on the Billboard Hot 100 chart and led to her winning the Grammy Award for Best New Artist the following year. Boone later focused her music career on country music resulting in the 1980 No. 1 country hit "Are You on the Road to Lovin' Me Again". In the 1980s, she recorded Christian music which garnered her four top 10 Contemporary Christian albums as well as two more Grammys.

During 1981-82, Boone toured the United States in a production of the stage adaptation of the film Seven Brides for Seven Brothers. The play was a commercial and critical success nationwide before opening on Broadway in July 1982. The Broadway reviews were lackluster, but a scathing review by The New York Times led the show to close after just five performances. The day after the show's closing, several of the show's stars and theatergoers protested the closing outside the New York Times' building, hoping for a retraction of its review and the re-opening of the show. But, despite the enthusiastic reception of the show from Broadway theatergoers, the producers believed that the show could not overcome its reviews and the show remained closed.  Boone continued her theater work, appearing periodically in stage productions nationwide including lead roles in Camelot, Meet Me in St. Louis, Mississippi Love, South Pacific, The Human Comedy, and The King and I. Boone returned twice to the New York stage. She starred as Maria in the 1990 Lincoln Center production of The Sound of Music, which was nominated as Outstanding Musical Revival by the Drama Desk Awards. In 1996, Boone played against her image as Rizzo in the 1990s revival of Grease.  In 1978, Boone made her first foray into television with a musical adaptation of O. Henry's The Gift of the Magi co-starring John Rubinstein. She also headlined two of her own NBC television music specials - The Same Old Brand New Me (1980) and One Step Closer (1982). In 1984, Boone appeared in the television movie Sins of the Past co-starring Anthony Geary, Barbara Carrera and Kim Cattrall. In the film, Boone portrayed Clarissa Hope, a young prostitute who leaves her job after a fellow prostitute is murdered, and subsequently reforms herself as a Christian music singer. The film was a Top 10 Nielsen hit. Boone has since made guest appearances on several television shows including Step by Step and Baywatch Nights and was featured in the television films Come on, Get Happy: The Partridge Family Story and Treehouse Hostage.
