With the success of Eric Idle 's musical retelling of '' Monty Python and the Holy Grail '' , called '' Spamalot '' , Idle announced that he would be giving '' Life of Brian '' a similar treatment . The oratorio , called '' Not the Messiah ( He 's a Very Naughty Boy ) '' , was commissioned to be part of the festival called Luminato in Toronto in June 2007 , and was written/scored by Idle and John Du Prez , who also worked with Idle on '' Spamalot '' . '' Not the Messiah '' is a spoof of Handel 's '' Messiah '' . It runs approximately 50 minutes , and was conducted at its world premiere by Toronto Symphony Orchestra music director Peter Oundjian , who is Idle 's cousin . '' Not the Messiah '' received its US premiere at the Caramoor International Music Festival in Katonah , New York . Oundjian and Idle joined forces once again for a double performance of the oratorio in July 2007
