The Gaither Vocal Band is an American southern gospel vocal group, named after its founder and leader Bill Gaither. On March 1, 2017, it was announced that the Gaither Vocal Band lineup consisted of Reggie Smith, Wes Hampton, Adam Crabb, Todd Suttles, and Bill Gaither, as of April 1. Although the group started out recording contemporary Christian music in the 1980s, it became known for southern gospel after the popularity of the Gaither Homecoming videos. The lineup of the band changes often, with artists leaving to work on solo careers, and new and old ones coming to replace them.

Michael English was hired as the new lead singer, so McSpadden was moved down to baritone, and Gaither dropped to the lowest part. At this point the group dropped the "new" part of their name. Although the previous album (New Point of View) had been more contemporary than its predecessors, the album with this version of the group (One X 1) took it even further. After this album, Larnelle left and was replaced by Lemuel Miller. The group did not record an album with Lemuel before he too left. He was replaced by Imperials alumnus, Jim Murray. This line up cut one album (Wings) before Gary McSpadden left to start his solo career. Mark Lowry was convinced to replace him. Along with a great voice, Lowry added comedy to the mix. Their Gospel roots project Homecoming in 1991 caused most Southern Gospel fans to welcome the Vocal Band with open arms. Jim Murray left and was replaced by Terry Franklin. The album Southern Classics was released in 1993 with the hit "I Bowed On My Knees". Later Michael English left. He was replaced by Buddy Mullins. Mullins was only a temporary fill-in, but he was included on the album Testify. Terry Franklin soon left and was replaced by yet another Imperials alumnus, Jonathan Pierce (formerly known as Jonathan Hildreth, his first and last name--then changed to his first and middle name). Strengthened by the popularity of the Homecoming video series, the Vocal Band added Guy Penrod at lead. After Pierce's departure, Gaither hired David Phelps at tenor. After Lowry's departure, Imperials alumnus Russ Taff sang baritone for a couple of years. Marshall Hall was his replacement. Wes Hampton succeeded Phelps in 2005. The group has had three number one songs on the Singing News chart. "Yes, I Know" held the top position from July to October 1997, as did "I Will Go On" in November 2006. "Greatly Blessed" was their third number one single. The group has routinely performed classic Southern Gospel songs including many written by Bill and Gloria Gaither like "He Touched Me", "I Believe In A Hill Called Mount Calvary", and "Sinner Saved By Grace."
