It takes place in medieval England and here — A.D. 932 and now.

Many in the opening night audience knew almost every move in the Aurora Fox staging of “Monty Python's Spamalot” — singing along on “Always Look on the Bright Side of Life” and other songs by Eric Idle, the former Monty Python member who wrote the book and lyrics and collaborated on the music with John Du Prez.

They also started to laugh before the first pronouncement from the stilt-walking Knight of Ni and were appropriately bedazzled by the wonderful Sarah Rex as Lady of the Lake.

They were ready for killer rabbits and flying cows and the “bring out your dead” scene (“I'm Not Dead Yet”) — and impressed that the Black Knight bit was pulled off successfully. The wise-head French guard brought another round of laughter as skilled director/choreographer Piper Lindsay Arpan's experience with the show brought it all together. (She performed in it on Broadway and in the national touring show.)

Throughout, the cast performed with tongue firmly in cheek in this charming spoof of the King Arthur legend — including the apparently clueless king, played by mellow-voiced Stephen Day. Costumes verged on cartoon versions of medieval garments and the set has castles walls and crowded streets, with assorted imaginative props. One needs to pay attention to detail for full enjoyment.

I'm certain that with a few more performances under the belt, comic timing will be even better.

The musical is based on the film, “Monty Python and the Holy Grail,” a clever and silly spin on the King Arthur legend — reinvented with the fast-paced humor of the weekly “Monty Python's Flying Circus” television programs, beloved my millions.

Nimble character and costume changes prevail: Daniel Langhoff is a goofy Sir Galahad (et al) and Michael Bouchard plays the timid Sir Robin (et al). Kurt Brighton is Sir Lancelot (et al); Jim Hindsley is Sir Belvedere (et al); Liam Speros is Prince Herbert (et al); and the nimble Bob Hoppe is King Arthur's faithful servant Patsy, he who clacks the coconut shells as they canter along — and sometimes trot.

Camelot it's not — but it's an entertaining evening for those who are somewhat familiar with the territory.
