The tale of the king of the Britons starts, as you do in Pythonland, with a Finnish fish-slapping dance. However, we are soon on-script with “the lovingly ripped off” Monty Python And The Holy Grail – with jazz hands.

Eric Idle, who appears as God in video form has, alongside John Du Prez, added some lovely Broadway parodies – The Song That Goes Like This being pure Rutles meets Lloyd Webber.

Marcus Brigstocke is an engaging king, while Todd Carty is lovable as gormless Patsy – with half-coconuts, of course – and a surprising highkick (even for a horse).

All the Holy Grail set-pieces are here, from the Black Knight who wants to call his duel with Arthur a draw, despite having all his limbs hacked off, to an outbreak of taunting in an outrageous French accent, with an avalanche of raspberries (and the odd elderberry) thrown in.

Brigstocke and Carty are joined by a multi-talented cast, with Jon Robyns (Galahad), Graham MacDuff (Lancelot) and Rob Delaney (“Brave” Sir Robin) standing out as quick-changing comedy turns Python would be proud of.

Scene-stealer extraordinaire, however, is Lady of the Lake Jodie Prenger, who has a fabulous singing voice and tremendous comic timing, highlighted in The Diva’s Lament.

The swearing isn’t too bad, with enough nudge, nudge material to fly over little ones’ heads. The sets are dazzling – Gilliam meets illuminated manuscript – and with Always Look On The Bright Side Of Life thrown in for good measure, Spamalot is paradise for silly billies, whatever the age.
