It remains one of the most iconic comedy series of our time, spawning films, books, records and tours - and even now as it nears its 50th anniversary next year, Monty Python is as loved as ever.
Coinciding with the milestone, founding member Eric Idle, 75, has written his 'sortabiography', Always Look On the Bright Side Of Life, which charts some of his recollections of the series and its spin-offs.
Idle, John Cleese and Graham Chapman worked together at the Cambridge Footlights (Cambridge University's now famous dramatics club), later meeting their Oxford Revue rivals Terry Jones and Michael Palin at the Edinburgh Festival.
Terry Gilliam, whose animations would form a stream-of-consciousness flow to become the basis for Monty Python, was introduced to the gang after Cleese met him in New York when on tour with the Footlights Revue.
Did they think Python was going to be something big?
"Absolutely not. It was just a little late night show we were all doing, but which we were fortunate enough to have total control of. We weren't told what to do or stopped from doing anything. We suddenly had the opportunity to do a show exactly how we wanted to do it. That encouraged us to make it something completely different," Idle recalls.
They were given more freedom as the show started life as a late-night slot the BBC wanted to fill.
"There were fewer executives, who are, of course, the death of comedy. We had worked on light entertainment shows but didn't feel we belonged in that slot," adds Idle.
"Terry Gilliam made a tremendous difference because he was able to put that Victorian animated framework around it, which gave it a stamp look which other shows didn't have.
"The sketches appeared to be connected by this odd surrealistic framework," Idle recalls.
"Python wasn't a popular show at first. We really annoyed people. Middle-class ladies would say, 'Monty Python! We hate you lot!' It was much more effectively insulting, rude and nastier than this cuddly group it now appears to be," says Idle.
"People didn't like our attitudes. We were mocking. Upper-class twits were mocked. All the things you were supposed to look up to were mocked."
The show originally ran for 45 episodes over four series. Idle still struggles to understand why it was such a hit. In his memoir, he notes that it was one of the first series shown in colour.
"Python isn't just one type of humour, it is a compendium of styles ... so there is visual humour, verbal humour, clever humour, silliness, rudeness, sophistication and brazen naughtiness, constantly alternating," Idle adds.
Monty Python first aired in 1969 with the six original members - Terry Jones, Michael Palin, Eric Idle, Terry Gilliam, John Cleese and Graham Chapman. Within 14 years, the Pythons had made five movies, 45 TV shows, five stage shows, five books, and countless records.
Of all the films, the religious satire Monty Python's Life Of Brian was the one which caused the most controversy. It's the story of an ordinary chap called Brian Cohen, who is constantly mistaken for being the long-awaited Messiah.
"We anticipated some controversy but not quite the outrage it aroused," says Idle.
"In America, it was on television news and they picketed the Warner Bros studios. We didn't have to do publicity on television for it because the protesters did it for us.
"In America some states banned it, so people would go to the next state to see it." Idle recalls.
"Usually, it was attacked by rather bigoted people who hadn't seen it and assumed it was blasphemous, which it actually wasn't. I think many good religious people actually liked it."
And of course, Idle's song - Always Look On The Bright Side Of Life - sung at the end of the film during the crucifixion scene, became iconic and went up the charts.
"People now sing it everywhere, at football matches and funerals. In fact, it's the number one song requested at British funerals."
In 1983, they released The Meaning Of Life, the last Python film.
"We'd pretty much done all we could. We'd done medieval history, we'd done religion and we'd done the meaning of life. It's a very long time for a group of chaps to be working together. People wanted to do different things."
The last time they got together was for the sold-out Python reunion shows in 2014.
"We had a lot of offers to tour it around the world, but Michael didn't want to do it so we didn't. But it was fun. I think it was a good call from him."
But what about now that the 50th anniversary is approaching - will they do another reunion show? It isn't sounding likely.
"Well, what would we do? Graham's dead, Terry (Jones) can't speak (due to dementia). You can only disappoint.
"We'll talk about something but I don't think we'll be performing," says Idle.
"But we are making a movie about Spamalot (adapted originally for the stage from Monty Python And The Holy Grail)."
