The extraordinary Scottish singer and guitarist Dick Gaughan has been grabbing audiences for four and a half decades with his mix of traditional ballads and agit-folk songs. Here in a special concert at London's Bush Hall, Gaughan shows why he has been such a defining figure of the folk revival, performing both solo and with a specially assembled star band of harpist Mary Macmaster, guitarist Martin Simpson and piper Michael McGoldrick. In the interweaving documentary footage, Gaughan shows the cameras around his hometown of Leith and travels to a festival appearance, giving insights into life on the road and what informs his passionate beliefs and work.
