"Double Barrel" is a popular 1971 reggae single by Dave and Ansell Collins, the second reggae tune to top the charts in the UK, following two years after Desmond Dekker's No. 1 ska breakthrough hit "Israelites".Written and produced by Winston Riley, former vocalist of The Techniques, the single featured the vocals of Dave Barker, who had been recording in Jamaica for around five years, principally for Clement "Coxsone" Dodd and Lee Perry.
