Monty Python Shows To Feature Stephen Hawking
Stephen Hawking is to appear in the Monty Python reunion shows which have just been opened up to another 6,000 fans.
John Cleese, Michael Palin, Eric Idle, Terry Gilliam and Terry Jones kick off the gigs on Tuesday and announced 600 extra tickets for each of the 10 dates at London's O2.
At a press conference in London, they revealed that Professor Brian Cox will star alongside Mr Hawking, who asked if he could feature because he is a "big Python fan".
It is the first time the members of Monty Python have performed together in the UK in over 40 years and tickets for the first show sold out in less than a minute.
They have had two weeks of intense rehearsals to prepare which Palin said was just the right amount: "We've got to be at a point that we're really enjoying it, we've got to feel like we did 40 or 50 years ago."
The 10 shows will see them perform in front of over 14,000 people and Palin joked that he had been dealing with the weight of expectation and excitement ahead of the shows with "difficulty".
The fast-paced comic revue requires the septuagenarian comedians to act, sing, dance and pull off rapid-fire costume changes.
Palin says they have drawn inspiration from the Rolling Stones frontman Mick Jagger, still gyrating at 70.
The dates will be the last for the group but as to life after Python, Gilliam said: "We are not retiring from life, just Python."
Cleese added that they had all gone their separate ways many years ago: "We have diverged enormously since we did the TV show. Michael does the travel programmes, Eric writes songs, I'm finishing my autobiography ..."
Palin reassured fans: "The main thing is we are not retiring, we will keep working until we drop."
The extra tickets go on sale from 6pm on Monday.
