A respected music teacher who wrote music teaching books for children was recently jailed for four years as a paedophile. One of his victims is asking for his books to be banned. Music teachers consider his books for recorder to be amongst the best music books ever written for children.
So...should the books be banned? Do we separate the artist from his work?
