Medley and Hatfield both possessed exceptional vocal talent, with range, control and tone that helped them create a strong and distinctive duet sound and also to perform as soloists. Medley sang the low parts with his deep, soulful bass-baritone, with Hatfield taking the higher register vocals with his soaring tenor.
They adopted their name in 1962 while performing together in the Los Angeles area as part of a five-member group called The Paramours., which featured John Wimber, one of the founders of the Vineyard Movement, on keyboards. At the end of one particular performance, a Marine in the audience shouted, "That was righteous, brothers!", prompting the pair to adopt the name when they embarked on a career as a duo.
