LONDON — Comedy troupe Monty Python said Monday it will extend the run of its stage show, which was unveiled last week.

The show at London’s 20,000-seat O2 Arena will now run from July 1 to 5 next year.

The first show sold out within 43.5 seconds, organizers said.

A sixth show is being planned for the Hollywood Bowl in L.A., where the Pythons’ performed a live gig in 1980, according to the Daily Mail newspaper. The Daily Mirror reports that a source has told them the Pythons are also considering a world tour.

The show reunites John Cleese, Eric Idle, Terry Gilliam, Michael Palin and Terry Jones. The sixth Python, Graham Chapman, died in 1989. Eric Idle said last week that Chapman would “take part” via comedy seance.
