Merchant's first success as a calypsonian came in 1977 with "Um Ba Yo" and "Let No Man Judge". The following year he made it to the finals of the Calypso Monarch Competition with "Norman, Is That You", which was inspired by the 1976 movie,
Norman... Is That You? He made the finals again in 1985 with "Pan in Danger" and "Caribbean Connection". In addition, The Original de Fosto Himself and De Mighty Trini (Robert Elias) made it to the Calypso Monarch finals with calypsos written by Merchant. He was also a prolific composer. Daniell said that while Merchant had recorded about fifty calypsos, he had written close to 500. Although many of his compositions were uncredited, other singers he is known to have written for included Bally (Errol Ballantyne),
Baron,
Crazy,
Drupatee Ramgoonai,
Eddy Grant, and King Austin, and the bands
Atlantik and
Byron Lee and the Dragonaires. == Composition and style ==
