The Equals were kind of formative for later British bands. They led the way for future racially integrated bands on the island. The specials and really most the 2nd wave ska bands were into them. They influenced the Clash, who covered the Equals "Police on my Back."
The lead singer was Eddie Grant who you might remember from his solo hit "Electric Avenue." Eddie moved back to the Caribbean after the Equals and shook up some of the strong divisions between different Caribbean music styles, getting people from various backgrounds to record and collaborate with each other. It was almost a music revolution but not quite.
