Think these bands were more on the lighter/Lover's side. Coxsonne Dodd was an old mate of Murray from Murray's Music City in Brook's Bar, then later Princess Road. I doubt whether he ever travelled with the sound though, think maybe it was his son and/or heir.
Clement Seymour "Sir Coxsone" Dodd, CD (Kingston, Jamaica, January 26, 1932 – May 5, 2004) was a Jamaican record producer who was influential in the development of ska and reggae in the 1950s, 1960s and beyond. He received his nickname "Coxsone" at school: because of his teenage talent as a cricketer, his friends compared him to Alec Coxon, a member of the 1940s Yorkshire County Cricket Club team.
