The stars of legendary comedy troupe Monty Python decided to reunite for a live performance after South Park creators Matt Stone and Trey Parker begged them to make a comeback.

The five funnymen - John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin - confirmed on Thursday (21Nov13) that they are getting back together for a huge show at London's O2 Arena in July (14).

It will be their first time working together in 30 years, and Jones has now revealed the unlikely inspiration behind their reunion.

He tells London newspaper Ham & High, "The South Park people brought us together, Matt Stone and Trey Parker. They approached us and suggested we should get together and do something together. That's what triggered the interest in the show."
