Not The Messiah (He's a Very Naughty Boy) is a comic oratorio based on Monty Python's Life of Brian, which retells the tragic tale of Mandy, impregnated by a Roman soldier, giving birth to Brian, a reluctant revolutionary of the People's Front of Judea who falls in love with Judith, gets mistaken for a Messiah and is arrested by the Romans and sentenced to be crucified. It ranges in reference from Handel, through a naughty Mozart duet, to the Festival of Nine Carols, Bob Dylan, and the classic finale "Always Look on the Bright Side of Life".
