The quality of the NT Live* productions has been such that I have happily stuck five stars on reviews of almost all of them. This creates a problem in the present instance, because for the sake of relative accuracy I need to award this show seven.
The production, in an encore season after first playing last year, is the funniest thing I've seen on stage since Edna Everage stormed the St James in 1993 and by some margin the most purely entertaining of the series so far.
The play, written by Richard Bean, is an adaptation of the 18th century Venetian commedia dell'arte Servant of Two Masters, in which Harlequin (the genre's customary characterisation of a hapless servant) simultaneously secures two positions and strives, with comic results, to keep each employer unaware of the other.
Bean's version transplants the action to Brighton in 1963 and its music-rich style - which includes a fab skiffle band during scene changes - tips a hat to the broad entertainments of the Palace Pier's golden days.
The plot is so involved as to defy synopsis, but briefly this Harlequin is Francis Henshall (Corden from TV's Gavin and Stacey), a failed skiffle player who lands jobs with two guvnors - Rachel (Rooper), a woman disguised as her dead twin brother, who was a petty hood, and Stanley (Chris), an upper-class twit who (yes, I know it's improbable) is Rachel's intended even though he killed her brother.
