The legendary troupe haven't performed live together in 34 years, but a deep love of comedy, an overwhelming desire to give back to their fans, plus the need to pay off some legal fees, finds the Pythons reunite one final time at the O2 in London. John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin are joined by Graham Chapman (courtesy of archive footage) and very famous special guests for an evening of classic songs and sketches.
