Idle enjoyed critical success with '' Rutland Weekend Television '' in the mid-1970s , out of which came the Beatles parody the Rutles ( responsible for the cult mockumentary '' All You Need Is Cash '' ) , and as an actor in '' Nuns on the Run '' ( 1990 ) with Robbie Coltrane . In 1976 , Idle directed music videos for George Harrison songs " This Song " and " Crackerbox Palace " , the latter of which also featured cameo appearances from Neil Innes and John Cleese . Idle has had success with Python songs : " Always Look on the Bright Side of Life " went to no. 3 in the UK singles chart in 1991 . The song had been revived by Simon Mayo on BBC Radio 1 , and was consequently released as a single that year . The theatrical phenomenon of the Python musical '' Spamalot '' has made Idle the most financially successful of the troupe after Python . Written by Idle ( and featuring a pre-recorded cameo of Cleese as the voice of God ) , it has proved to be an enormous hit on Broadway , London 's West End , and Las Vegas . This was followed by '' Not the Messiah '' , which repurposes '' The Life of Brian '' as an oratorio . For the work 's 2007 premiere at the Luminato festival in Toronto ( which commissioned the work ) , Idle himself sang the " baritone-ish " part
