"Stratford East has always maintained its gorgeous traditional scarlet and gilt, along with its onstage iconoclasm. The Infidel – the Musical is its best tribute for ages to Joan Littlewood’s theatre. It’s bawdy. The risks it takes are real. It has, without being po-faced, a healing purpose. Actually, there has not been anything since Jerry Springer – the Opera that targeted religious zealots so exuberantly. Unless you count The Book of Mormon, which I don’t, thinking it plenty rude and finely drilled but toothless"
