Made in Dagenham

In London 1661, Charles II has been crowned and the Restoration has begun. Lust is based on Wycherley’s The Country Wife ,written in 1675, and celebrates the noblest urge bestowed on us. This romantic comedy throws off the shackles of Puritan austerity. Horner, a notorious libertine, charms an seduces his way into the hearts of ladies of quality.

Dates: Tuesday 29th March 2021 to Saturday 2nd April 2022
Location: BRENTWOOD THEATRE, 15 Shenfield Road Brentwood Essex CM15 8AG


This amateur production of “Lust” is presented by special arrangement with SAMUEL FRENCH LTD. A Concord Theatricals company.

Written by Heather Brothers. Based on William Wycherley’s – A Country Wife



“He's very watchable as the charismatic shyster “Professor” Harold Hill – confidently talking the talk, eyeing up the folk of River City from front stage, enjoying a great vaudeville duet with Matthew Carpenter as his old mate Marcellus, flirting suavely with his Librarian Marian – an excellent performance from Anna Green, even if it's hard to see her as an old maid ”

Michael GrayThe Music Man

“Costumes were excellent and the lighting was very well designed and beautifully executed. It is lovely to see full houses for any society so well done the Billericay for another entertaining show.”

“ The Quartet, also known as the school board, started off as people who couldn't get along, but when convinced to sing by Harold, could not be separated. This group of four, Jeremy Martin, Niels Bradley, Nik Graham & Ray Bowler, probably had the hardest sing of the show having to perfectly coordinate and harmonise, something they did well enough.”

The Unnamed Critic The Music Man

“I was intrigued to see how Billericay Operatic Society would manage to perform the show in such an intimate venue. The answer is very well indeed! Having only seen The Producers in large theatres before, with lavish sets, it was an eye opener, for me, to see that it could be done on a smaller scale. Whilst it was impractical to do the large, showpiece, dances that were in the original show, choreographer Jane Granby did create the effect that was required of the script.”

Tessa DaviesThe Producers

“Costumes were excellent, the attention to detail was superb and, yes, I did notice that the ladies had brooches on their coats, absolutely right for the period. It is the small touches like these that make the difference to the ‘look’ of the show. As a costume designer myself, I would congratulate the costumes and props team. I think that the Betty puppet was produced by the company, if so, it was excellent.”
