In the early sixties a vocal group was formed by George Clive Murphy and the late Maurice Prof. Johnson. Called THE TENNOR TWINS at first, both singers performed together at numerous venues on many occasions. THE TENNORS was born when the duo was later joined by Norman Davis, at which time Prof. Johnson became the lead vocalist. It was at the legendary Studio One, owned by Sir Coxone Dodd, that these first recordings were done and released under the Downbeat label. Their song PRESSURE AND SLIDE was their first recording and became the biggest hit in Jamaica for the year 1967.
