By 1960, Morgan was the unrivaled King of Ska -- at the peak of his popularity, he was the first and only Jamaican artist to date to hold down the top seven slots on the national pop singles chart during the same week, generating a string of smashes including "Be Still," "In My Heart," "Don't Call Me Daddy," "Moon Hop" and "Meekly Wait and Murmur Not." In 1961, he recorded his biggest hit ever, "Housewives' Choice," and a year later -- in celebration of Jamaica's emancipation -- recorded the first independence song, "Forward March." Morgan and Prince Buster, arguably the two biggest ska performers of the era, became embroiled in a fierce musical feud which quickly spilled over among their respective fans, and as of 1963 disputes between the two camps became so heated that leaders of the newly formed Jamaican government were forced to intervene, calling a cease-fire and bringing the two performers together for publicity photos to bury the hatchet.
In 1966, Morgan issued "Tougher Than Tough," widely credited as the first record in the rock steady genre. He continued to innovate in the years to follow -- among his most enduring contributions were "Went to the Hop" (the first Jamaican song with an electric bass guitar), "Blazing Fire" (the first song to employ an electric piano), "Love Not to Brag" (the first duet with a female artist, Millicent Patsy Todd) and "Seven Letters" (the first reggae song, produced in collaboration with brother-in-law Bunny Lee). Morgan also produced many of the era's most notable up-and-comers, among them Bob Marley, Jimmy Cliff and Garnet Silk. Although he lived in Britain from 1963 onward, Morgan remained a towering figure in Jamaica throughout the remainder of the decade; even after his fame began to slip in the 1970s, he continued recording regularly in the years to follow.
