Like relationships, not all musical partnerships are plain sailing. 'I just get tired of Junior sometimes,' guitarist Buddy Guy once said of long-time harmonica-playing companion Junior Wells, adding: 'I look into his face more than I do my wife's.' Nevertheless, during the course of their quarter-century of musical 'marriage' they made some classic blues recordings. We feature Guy and Wells playing separately and, live, together, as well as their pairings with others.
