Leon Rosselson has been at the forefront of songwriting in England for over sixty years. He started his performing career in the early days of the folk revival as a member of the Galliards with whom he made many radio and TV broadcasts and concert appearances. He began writing songs seriously (and humorously) in the early 1960s and has yet to stop. His early songs were topical-satirical, but he broadened out from there, absorbing different influences. He has performed at every conceivable venue around the UK and has toured worldwide. He has recorded many albums and published two songbooks. His song, "The World Turned Upside Down" was taken into the pop charts by Billy Bragg, and covered by artists including Dick Gaughan and Chumbawumba. Leon has also had 17 children's books published, the first of which, Rosa's Singing Grandfather was shortlisted for the Carnegie Medal in 1991.
