There is never a dull moment in this Alan Ayckbourn play, focusing on the complex love lives of four couples in the 1970s.

From start to finish, there is constant chatter and movement, all taking place in the bedrooms belonging to three of the pairs and focusing on their interconnected romantic relationships and friendships.

Black RAT productions have come up with some winning performance as they bound their way through this action-packed romp at Blackwood Miners Institute.

Middle-agd couple Ernest (Dudley Rogers) and Delia (Christine Pritchard) are celebrating their wedding anniversary but end up eating pilchards in bed and drinking tea instead of going out - meanwhile their wayward son Trevor ( Gareth John Bale) is out getting into extra-marital trouble at a friend's party.

Llinos Daniel is excellent as the wife Susannah in their troubled marriage, loudly chanting a confidence mantra each time she believes (mistakenly) that she is alone.

Lovey-dovey couple Kate and Malcolm (played by Lizzie Rogan and Keiron Self), sickeningly self-absorbed, are hosting the party - at first they seem a little light relief as the only truly happy couple but even here the cracks start to appear!

Nick (Richard Tunley) is confined to bed with a bad back and remains there throughout, but his wife Jan (Lynne Seymour) goes off to the party to add even more confusion to the mix.

It's a typical farce, with everything that can go wrong doing so and the action speeding up gradually to the climax - but it is a witty script, expertly produced and performed by this group.

The travelling production premiered at Blackwood Miners Institute this week, and will be back in this area on November 15th at The Metropole in Abertillery and at the Congress Theatre in Cwmbran on November 20th.
