Sure, you’ve heard of the Rat Pack, but did you know there was a Caribbean branch of that famous menagerie of Hollywood scene-makers? Even more intriguing, the defacto head of the tropical chapter of Bogie’s bunch was none other than the dashing duellist Errol Flynn. In 1946 Flynn tapped a local act known as the Navy Island Swamp Boys to be the house band for his personal island’s villa and rum bar. Schooled in “mento,” the indigenous music of Jamaica, Flynn renamed the band The Jolly Boys for its feel-good vibe. The group was billed as calypso music to affluent white tourists who flocked to the exotic retreat and carried the laid-back precursor to reggae back to their homelands.
