In 1963, Bob Marley, Bunny Livingston, Peter McIntosh, Junior Braithwaite, Beverley Kelso, and Cherry Smith formed a ska and rocksteady group, calling themselves "The Teenagers". They later changed their name to "The Wailing Rudeboys", then to "The Wailing Wailers", and finally to "The Wailers". By 1966, Braithwaite, Kelso, and Smith had left The Wailers, leaving the core trio of Marley, Livingston, and McIntosh. Marley took on the role of leader, singer, and main songwriter. Much of The Wailers' early work, including their first single Simmer Down, was produced by Coxsone Dodd at Studio One. Simmer Down topped Jamaican Charts in 1964 and established The Wailers as one of the hottest groups in the country. They followed up with songs such as "Soul Rebel" and "400 Years". In 1966, Marley married Rita Anderson, and moved near his mother's residence in Wilmington, Delaware, for a few months. Upon returning to Jamaica, Marley became a member of the Rastafari movement, and started to wear his trademark dreadlocks. After a conflict with Dodd, Marley and his band teamed up with Lee "Scratch" Perry and his studio band, The Upsetters. Although the alliance lasted less than a year, they recorded what many consider The Wailers' finest work. Marley and Perry split after a dispute regarding the assignment of recording rights, but they would remain friends and work together again. Between 1968 and 1972, Bob and Rita Marley, Peter McIntosh and Bunny Livingston recut some old tracks with JAD Records in Kingston and London in an attempt to commercialize The Wailers' sound. Livingston later asserted that these songs "should never be released on an album . . . they were just demos for record companies to listen to". The Wailers' first album, Catch A Fire, was released worldwide in 1973, and sold well. It was followed a year later by Burnin', which included the songs "Get Up, Stand Up" and "I Shot The Sheriff". Eric Clapton made a hit cover of "I Shot the Sheriff" in 1974, raising Marley's international profile. The Wailers broke up in 1974 with each of the three main members going on to pursue solo careers. The reason for the breakup is shrouded in conjecture; some believe that there were disagreements amongst Livingston, McIntosh, and Marley concerning performances, while others claim that Livingston and McIntosh simply preferred solo work. McIntosh began recording under the name Peter Tosh, and Livingston continued as Bunny Wailer.
