Props, costumes and stage sets for the forthcoming Bristol Gang Show have been badly damaged when a storage warehouse flooded.

Items due be used in show in February were left under 2ft of water when a pipe burst at the show's storage building in St John's Lane, Bedminster.

But the team of volunteers behind the show say they will put in extra hours to make repairs and carry out rebuilding work to ensure the production goes ahead as planned.

The stage crew for the Bristol Gang Show, which will be staged at the Bristol Hippodrome between February 18 and 21, discovered the damaged props, costumes and stage scenery last Monday morning.

Chris Le-Petit, stage manager for the Bristol Gang Show said: "We were shocked to see the damage to the scenery for this year's show, but our team of volunteers have committed to working all the hours required to ensure that it will not affect the sets designed."

James Haworth, chairman of the Gang Show management team, said: "The show will go on, and we will not allow this setback to affect the opportunity that the show provides for the young people onstage.

"Obviously, we are extremely grateful for the support from our volunteer teams, and I have every confidence the sets will be the best built ever.

"We've removed a lot of things and started repairing some of the scenery which was broken. The water must have been down there for a while because everything was badly damaged.

"Our costume archive stretching back 30 years was damaged and we will have to get rid of most of it.

"We've turned off the water and cleared out some sections of the warehouse. We've got insurance in place but we're not sure it's worth claiming because of the excess."

The Bristol Gang Show is returning to the Hippodrome this year after an outcry from Scouts over its cancellation.

The theatre called off the popular variety show earlier this year, despite hosting it for nearly 40 years.

Hippodrome management cited safety reasons when they broke the news to Avon Scouts that the show could not go on in October.

The decision sparked a storm of protest from the show's cast, as well as behind-the-scenes volunteers, parents, previous performers and theatregoers.

So talks between show organisers and the theatre led to new dates being arranged, and six performances will take place in the school holidays – evenings and two matinees.

Avon Scouts' assistant county commissioner, Philip Bird, said the production was a showpiece for the Scout movement and the youth of the Bristol area.

With a cast of 89 from the Scouts, supported by a team of backstage volunteers, rehearsals for the show, described as a fast-moving variety show full of songs, dance and sketches, started in July.

Tickets are £10.50 with discounts for children and senior citizens. Family tickets and group discounts are also available.

Tickets can be bought from the Hippodrome Box office Monday to Saturday between 10am and 6pm (8pm on performance days).
