The Heptones is a Jamaican rocksteady and reggae vocal trio. The trio consist of Leroy Sibbles, Earl Morgan and Barry Llewellyn. They group together in 1965 in Kingston, Jamaica. The trio was formerly using the name "Hep Ones" but changed it later and it become "The Heptones". It was chosen by Morgan when he saw a bottle lying in the pile.
The trio recorded for most of Jamaican record producers during that time. They began their career after the release of unsuccessful single for Ken Lack's "K Calnek" label under the supervision of Coxsone Dodd of Studio One. The Heptones had several of Jamaican hits for Studio One which begin with "Fattie Fattie" (their first Studio One single in 1966). It start a long way of success for Coxsone which include the songs "Get In The Groove", "Be a Man", "Sea of Love", "Ting a Ling", "Party Time" and "I Hold the Handle", "Pretty Looks Isn't All". The Heptones were the major rivals to "The Techniques" that recorded for Arthur "Duke" Reid as the number one vocals of the rocksteady era. In 1973, they had a major hit with "Book of Rules" (it was based on an American poem called "A Bag of Tools" by R.L.Sharpe). It was one of the trio's several songs not sung by Sibbles. Barry Llewelyn sang and co-wrote "Book Of Rules". Leroy Sibbles moved to Canada in 1973 and the trio stop recording but he return in 1975 to again record again at Harry J's Kingston studio.
