This is a little diamond of a show with songs by the mile and a high-energy feel-good drive about it that leaves you feeling euphoric and somehow happy with the world.

Clearly the show is an extension of the Dreamboats and Petticoats franchise, with everyone now in the rock ‘n’ roll sixties, that bygone age when everything seemed so new and exciting and The Beatles were showing us how you didn’t need a posh background or a fancy education to succeed to wealth and fame.

The social background here proves the point. We are among a crowd of late teens early twenties grafters from somewhere in Essex. The accents are similar to TOWIE, but the IQs are several degrees higher.

Everybody gives life a whirl at the social club where new tunes are dreamed up with mod wannabes hankering for a slot on Ready Steady Go .As one character proves conclusively, you can work down the drains all day but sing convincingly in a rock band all night – sewage proving no handicap at all.

The young company (directed so beautifully by Bill Kenwright and Keith Strachan who set all this before us with experienced flair) are consistently marvellous and generate a great sense of sheer well-being. They wear their beehives, Sixties geometric frocks and snake hip slacks with great panache and do their damnedest to give the songs as much welly as is humanly possible, which drew cheers from the audience (Pretty Woman took the roof off)

Although it is invidious to single out individual performers from a talented company, I must mention Alex Beaumont and Elizabeth Carter as the love interest Bobby and Laura. The dialogue is frequently trivial and without much depth, but it was made for the show and fits the occasion perfectly, and so these two young performers, who are wonderful to watch, work harder than ever to convince us that Bobby really is not a snake in the grass and really does love Laura.

In recent days I saw the RSC’s Henry IV 1 and 2. The theatrical clout at Stratford was totally admirable, but it was also a quality mirrored here, proving that energy, commitment and theatrical flair are not necessarily confined to our national companies but can illuminate a smaller scale touring company such as this one.

Runs until Saturday, October 25.
