The Jordanaires

The Jordanaires were an American vocal quartet that formed as a gospel group in 1948. Over the years, they recorded both sacred and secular music for recording companies such as Capitol Records, RCA Victor, Columbia Records, Decca Records, Vocalion Records, Stop Records, and many other smaller independent labels.

In the mid-1950s, with a lineup of Gordon Stoker (first tenor), Neal Matthews (second tenor and lead vocals), Hoyt Hawkins (baritone and lead vocals), and Hugh Jarrett (bass vocals), they also began lending their vocal talents to other artists as background singers in recording sessions. They are widely known for having provided background vocals for Elvis Presley in live appearances, recordings, and feature films from 1956 to 1970. Jarrett was replaced by then-teacher Ray Walker in 1958. The group worked in the recording studio, on stage, and on television with many country, gospel, and rock and roll artists.

They also provided background vocals using the names the Gordonaires (a play on the name of the group's first tenor Gordon Stoker), the Merry Melody Singers, and the Almanac Singers, sometimes using different personnel. Provided by Wikipedia
