The theatre began life as a small concert room above the stables of the Royal Standard Hotel, a small hotel and tavern built in 1832 at what was then 522 Stockbridge Terrace, on the site of the present theatre – not, as sometimes stated, on land where the train station now stands.

The original design featured a sliding roof that helped cool the auditorium during intervals in the summer months.

It received such amusingly bad reviews that it became a cult hit and played to full houses for 278 performances before transferring to two other West End theatres.

Headlining the bill from his radio series was Will Hay, with his schoolboy retinue of Charles Hawtrey and John Clark, and among the "turns" was Stainless Stephen, a comic acrobat comedian duo, and Victor Barna (then world champion table tennis player) giving an exhibition, who would invite audience members up on to the stage to see if they could beat him in ten points.

From 1947 through 1962, Jack Hylton produced The Crazy Gang series of comedy revues, with a glittering company of variety performers including Flanagan and Allen, Nervo and Knox, and Naughton and Gold.
