Monty Python was the 1970s British comedy troupe that became a cult icon, and shot its members like John Cleese and Eric Idle to fame. It had 6 members. But only devout fans know about the Seventh Python, Neil Innes. The British comedian tells us about writing for Monty Python's Flying Circus, being crushed by a giant rabbit for "The Holy Grail," the Rutles (his Beatles spoof band), how he made the whistle behind "Always Look on the Bright Side of Life" famous, and what it's like being lucky Python No. 7.
