A single on the London label's Reggae Series from 1970. Ken Lazarus does a passable enough version of he Maytals "Monkey Man" and the more interesting "Bongo Nyah" on the flip.Not much about Ken on the internet but did find this -
"Jamaican ska and reggea singer. Probably best known for his work as a lead singer in Byron Lee's Dragonaires band. In the early 60s the band toured extensively in the Caribbean which made Ken Lazarus a popular singer on the island. He also became famous as a highly commercial cover artist. Later on he changed his style, recording roots and culture sides."
