The Mountain City Four were a Canadian folk music group, based in Montreal and active from 1963 to 1967. The group consisted of Jack Nissenson, Peter Weldon, Kate McGarrigle and Anna McGarrigle. They are primarily remembered for popularizing a number of songs by Wade Hemsworth, including the National Film Board animated short The Log Driver's Waltz, as well as for Nissenson's recording of Bob Dylan's 1962 Finjan Club concert in Montreal.
