The dead parrot routine, the Spanish Inquisition and the silly walk will all be performed on stage this week for what the five remaining members of the Monty Python comedy team, all in their 70s, said Monday will probably be their last reunion.

"Monty Python Live (mostly): One Down, Five to Go" opens at London's cavernous O2 arena on Tuesday for 10 performances, with the last one on July 20 to be broadcast worldwide.

In addition to famous Python skits, it will be a fully staged theatrical extravaganza with dancers and an orchestra. It will also feature a filmed appearance by Python Graham Chapman, who died in 1989, and a cameo for British theoretical physicist Stephen Hawking, the Pythons said at a news conference.
