Eric Idle (born 29 March 1943) is an English actor, comedian, author and musician. Idle is a former member of the British surreal comedy group Monty Python, a member of the parody rock band The Rutles, and the writer of the music and lyrics for the Broadway musical "Spamalot" (based on "Monty Python and the Holy Grail"). Known for his elaborate wordplay and musical numbers, Idle performed many of Python's songs, including "Always Look on the Bright Side of Life" (from "Life of Brian"), and the "Galaxy Song" (from "The Meaning of Life"). After "Monty Python's Flying Circus", he hosted "Saturday Night Live" in the US four times in the first five seasons.
