(10 January 1934 – 9 August 2013) Louisa Jo Killen (né Louis Killen) was one of the most widely influential musicians of the folk revival and a key voice of English traditional song. She was a hard-core, unadulterated folksinger whose passionate delivery was matched by a deep and wide-ranging knowledge of the songs and the working people who made them. Born and raised in the heart of the industrial North East of England, she came early to a love of folk music.
