Presenter Alan Yentob sits down and catches up with the Monty Python crew ahead of their huge show at the O2 in London in July. The show is a reunion of sorts, but also a farewell, and in an effort to find out the real answer to the question 'why now?', given the loss of Graham Chapman and so many years since their last show, he grills Cleese, Palin, Gilliam, Jones and Idle about all things Monty Python. There's also coverage of each of their own individual projects that they have coming up after the run finishes, as well as getting some exclusive access to the rehearsals of the show itself, which will be a must see for any fans of one of the most iconic comedy groups that there has ever been.
