The duo of Michigan (Anthony Fairclough) and Smiley recorded at Clement "Coxsone" Dodd's Studio One in Jamaica, pressing their first number one hit single, "Rub a Dub Style", which featured their call and response style vocals, overdubbed on the Studio One riddim, "Vanity" (the instrumental alias given to Alton Ellis' Rocksteady classic, "I'm Just A Guy").
