The seeds of his future career had been sown near the end of the 1950s, when he witnessed the American folk icon Pete Seeger at a gig in Glasgow playing banjo. MacKintosh immediately bought one and immersed himself in the Scottish folk scene; though he also played harmonica and concertina, the five-string long-neck banjo became his instrument of choice.
One frequent topic among MacKintosh fans concerns the question: What makes him the stage presence he is? The man is no banjo (or concertina, or bagpipe) virtuoso - as he would be the first to admit. His voice is agreeable, but not great. He is no eccentric in either apparel or demeanour. During his concerts nothing happens. He just stands there on stage, moves his fingers to play the banjo, moves his mouth to sing, and uses facial expressions - sparingly - to project moods. And yet, there is such a lot going on between him and his audience.
