What do you get when you put together four talented policemen who happen to play instruments and sing better than your average cop? The answer -- a folk-pop group called Brothers-in-Law. Guitarists Larry Reaume and Howard Duffy, bassist Ken Clarke, and banjo-picker Alec Somerville began moonlighting as Brothers-in-Law in late November of 1963. The foursome did small local gatherings at first, creating a loyal band following almost accidentally. The group's music is comparable to that of the Westerleys, Crosby, Stills & Mash, or the Dillards.
