If you are going to revive a Tom Stoppard play, it seems perverse - with so many to choose from - to opt for one of his lamest: his 1983 adaptation of Ferenc Molnar's Play at the Castle. This is froth, nothing more. Having said that, Salisbury's artistic director, Joanna Read, makes a fine job of it, giving this farcical tale set on a 1930s ocean liner the kind of classy production it demands. Nancy Surman's Art Deco design recreates a bygone era of opulent elegance. The evening is as easy on the eye as it is on the brain.

Sandor Turai (Matthew Kelly of Stars in Their Eyes fame) and Alex Gal are famous playwrights about to premiere their latest musical comedy in New York. Joining the ship earlier than expected, they overhear the play's leading lady, Natasha, canoodling with her former lover and the play's leading man, Ivor Fish. This is a disaster because in tow with the playwrights is Adam Adam, their protégé and composer, and Natasha's fiancé. So Turai concocts a scheme that will save both Adam and Natasha's relationship and the play.

That is about it, folks. The play is such a trifle that you are still waiting for it to really get going when it rolls to a close. It is all mildly entertaining and full of the kind of Stoppardian wordplay and punning that will either make you grin or groan. But it is never farcical enough to be really funny or sufficiently substantial to be satisfying and, most damagingly, Stoppard never successfully persuades that there is anything really at stake to make such a song and dance about.

Singing and dancing are integral to the plot. After a hesitant start, Read keeps up a good pace, the cast work like demons and, in the play's best part - that of the steward Dvornichek who gets everything wrong - John Ramm puts you in mind of the loveable roguishness of the late Leonard Rossiter.
