Shervington began his career in the early 1970s as a member of the showband Tomorrow's Children. Inspired by the success of Ernie Smith's "Duppy or a Gunman" and Tinga Stewart's "Play de Music", both delivered in heavy patois, he recorded "Ram Goat Liver" in a similar style. The follow-up single, "Dat" - about a Rastafarian trying to buy pork (without naming it aloud), contrary to his faith, so that he can afford marijuana - achieved considerable chart success internationally in 1976, reaching the number 6 spot in the UK Singles Chart.Trojan Records capitalized on this success by reissuing his first single, which peaked just outside the top 40 in the UK.
Shervington moved to Miami, Florida, in the early 1980s. He continued to record, and reached the UK top 20 again when "Your Honour" originally recorded in 1975 but never previously released, was re-issued in early 1982 together with a new recording "No Honour Among Tiefs" . Shervington often performs live in Miami, and periodically returns to his homeland for performances. As of 2007 he plays solo at Bahama Breeze in Kendall, Florida, and every other Sunday at Black Point Marina in Cutler Bay with a five piece band. Pluto appeared at the St. Kitts Music Festival on Friday 22 June 2007, sharing the bill with Steel Pulse and Sean Paul, among others.
