Indeed, fittingly for a show created by comedy gods, Eric Idle plays the Almighty - though not in person: his appearance is limited to a video projection that nonetheless is a pleasant addition to the show.
Stephen Tompkinson (who TV viewers will know from various primetime shows including Drop The Dead Donkey or Wild At Heart) is effective as King Arthur, adept at clowning and convincing as the exasperated leader of a higgedly-piggedly set of idiot knights.
Familiar scenes abound and those with even the slightest knowledge of Python will recognise the Knights of Ni, a deadly attack-rabbit and - inarguably one of the show's highlights - the fabulous and thickly-accented French soldiers who "fart in the general direction" of our crusaders.
Another splendid moment has to be the sing-a-long of 'Always Look On The Bright Side Of Life' - an uplifting anthem that doesn't fail to delight the mixed crowd of American tourists and Londoners of all ages.
The sparse set is used cleverly: watching the arms and legs fly off the infamous Python attacker who just won't quit a fight is as delightful for its primary school technicality (to call it 'wizardry' would be a step too far) as the gag itself.
Nods to modern-day events are thrown into the jokes to add a splash of freshness amidst ideas that were originally conceived almost 40 years ago. Snipes at Boris Johnson, Tesco horsemeat burgers and 'Plebgate' all warrant chuckles.
Standout stars in the musical's cast include Anna-Jane Casey as the impressively-voiced Lady of the Lake who craves more stage time and Rob Delaney as cowardly Knight of the Round Table Sir Robin and an effeminate, father-infuriating Prince.
For a big-name West End stage show there's a rag-tag feel to this production that only makes it more endearing. The costumes and props wouldn't look out of place in a local pantomime. When, at one point, the cast can't help but all crack up at their own hilarity it feels like the very best laughter should: the product of a joke that everyone is in on together.
Hats off then, to this wonderfully funny and very British treat. It might be snowing outside but in the Playhouse Theatre London the comedy is shining bright.
