Our House


Based in 1980s Camden Town, the Our House tells the story of London lad Joe Casey, who, on the night of his sixteenth birthday, takes Sarah, the girl of his dreams, out on their first date. In an effort to impress her with bravado, he breaks into a building site overlooking his home on Casey Street, which is owned by Mister Pressman, a high-end property developer. The police turn up, at which point Joe’s life splits into two: the Good Joe, who stays to help, and Bad Joe, who flees.

Featuring a collection of Madness hits including House of Fun, Baggy Trousers, Driving in my Car, It Must Be Love and of course Our House, the show is a huge hit with groups and schools looking for a very British musical.

Dates: Tuesday 12th March 2024 to Saturday 16th March 2024
Location: BRENTWOOD THEATRE, 15 Shenfield Road Brentwood Essex CM15 8AG

“Overall, I had a very enjoyable evening watching Lust the Musical. The company seem like a friendly group who obviously love what they’re doing and work hard. It was such a shame that they had to cancel their performance so close to opening last year but I can honestly say I am pleased that it’s the first musical I have seen since lockdown has ended and I look forward to seeing your next production.”

Zahna HullLust the Musical

“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.”

Tessa Davies Oliver!

“ 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.”
