It can be said that folk and rock music saved each other. Folk music gave rock content and lyrical depth while rock breathed new life into folk music, and provided a musical dynamism that took it to new and larger audiences. Neil Young, Denny Doherty, and Zal Yanofsky went from folk clubs to become major artists in folk based rock. The already established songwriters started recording and performing with electric bands while a new generation of folk artists and groups used elements of rock music to establish a new sound in Canadian folk music. Names like Perth County Conspiracy, Humphrey and the Dumptrucks, Fraser and Debolt and Three’s A Crowd became identified with a hybrid approach to folk music. Songwriters including Bruce Cockburn and Murray MacLachlan began to establish themselves as successors to the “big 4”.  In England, Pentangle and Fairport Convention defined a new approach to the interpretation of traditional songs and Canadians took note of new possibilities.
