As everyone above, I'm very sad to hear the news. Ian and his group were a major force in the Folk scene of the 1960s. Inspirational in many ways and both avant-garde and part of a folk establishment that set a quality standard that few could match.

He has left a considerable legacy of recorded music and is part of the four generations of Campbells that have found recorded success. The only other family I can think of that can match the four generations are Betsy Miller, son, grandson and great grandson (now in the group Bombay Bicycle Club).
