JB Priestley's farcical marriage comedy When We Were Married at the Maddermarket Theatre. Plus: The Comedy of Errors and two productions in Alan Ayckbourn's delightful Norman Conquests series.

WHEN WE ARE MARRIED

Maddermarket Theatre, Norwich, July 19-28, �12-�8, 01603 620917, www.maddermarket.co.uk

JB Priestley's farcical comedy, set in Yorkshire in 1908, tells of three eminently respectable couples whose lives are rocked by a scandalous revelation.

Married on the same day, in the same chapel and by the same cleric, these pillars of the community have joined together to celebrate their Silver Wedding anniversaries. However, the happy celebrations are brought to a sudden standstill with the discovery that due to a legal glitch they're not as respectably married as they thought they were.

Genevieve Raghu, artistic director at the Maddermarket, said: 'We've had great fun rehearsing this production – there has been a lot of laughter in the rehearsal room. But, whilst labelled as a farce, the way in which Priestley puts marriage under scrutiny also offers moments of heartache, betrayal and fear for what the future holds for these couples.'

THE COMEDY OF ERRORS

Sewell Barn Theatre, Constitution Hill, Norwich, July 19-21/25-28, �8 (�6 cons), 01603 697248, www.sewellbarn.org

Two sets of identical twins do not know of each other's existence, and farcical confusion occurs when all the twins converge in Ephesus.

One of William Shakespeare's earliest plays, The Comedy of Errors is also his shortest and one of his most farcical comedies. The audience can sit back and thoroughly enjoy the joke as the mayhem becomes even more ridiculous in this latest Sewell Bar theatre production.

Director Carole Lovett said: 'We have taken Shakespeare at his word that Ephesus, the island on which the action of the play takes place, is wicked, magical and difficult to find. To add to the feeling of remoteness from the real world we have moved the action to the farthest eastern reaches of the British Empire in the 1930s. This has proved an ideal backdrop.'

NORMAN CONQUESTS: ROUND AND ROUND THE GARDEN

Sheringham Little Theatre, until August 4, Mon-Thurs �15, Fri-Sat �16, �10 under-18s, matinees �13, 01263 822347, www.sheringhamlittletheatre.com

Sheringham Little Theatre's popular Summer Rep Season (running to September 8) continues with another of Alan Ayckbourn's delightful Norman Conquests series of plays exploring the lives and loves of the same eclectic mix of characters during a weekend visit to a relative's country house.

Following on from the first production Tables Manners (which returns on July 27/28/31) is Round and Round the Garden. Here we discover what went on outside during the disastrously eventful week-end at the home of Annie and her invalid mother.

Amorous assistant librarian Norman persists in the belief that at least one of the women will fall victim to his charms in spite of the presence of their husbands and other potential lovers. This continues to cause havoc among the rest of the guests with some unforeseen consequences.
