Summer may be over, but The Mill at Sonning is still very much in a holiday mood with Holiday Snap, an old-fashioned but uproarious comedy of mistaken identity and misunderstandings.

Written by Jon Pertwee’s brother Michael, and John Chapman, whose first play Dry Rot was staged, not surprisingly, at the Whitehall Theatre, it is the perfect vehicle for the irrepressible Royce Mills as a retired naval officer who is now a bumbling manager for a timeshare company in Portugal.

Armed with someone else’s spectacles and several pink gins, he causes great mayhem as he mixes up two adulterous couples in the sort of frolicsome farce of which he is a master, delivering his lines as if making them up along the way, and adding to the hysteria by corpsing.

As if his huge personality isn’t enough for one production, he is joined on stage by an equally incorrigible comic, Patrick Monkton, as a car salesman, on holiday with his boss’s wife, played with great aplomb by Felicity Duncan.

I wonder how director Ron Aldridge managed to keep Royce and Patrick under control during rehearsals. My guess is, he didn’t, but gave them the opportunity to let their comic genius run riot while still managing to work wonders to produce the sunniest of comedies.

Holiday Snap is at The Mill at Sonning dinner theatre, Oxfordshire, until October 3. Box office: 0118 969 8000.
