The Choral is set in the fictional mill town of Ramsden in 1916, which Ms Haliday, who has been part of the choir for 25 years, said was the first of many references to Huddersfield.
“Huddersfield is known as the town that bought itself, after the Huddersfield Corporation bought the land known as the Ramsden Estate in 1920,” she said.
“In the film, the choir is set to perform Elgar’s The Dream of Gerontius and we’re the choral society that made the first recording of Elgar’s The Dream of Gerontius.”
Having looked deeper into the choir’s archives, Ms Haliday found that in total 23 men had left the society to enlist in World War One, with two killed.
On 15 May 1915, Lance Corporal Lewis Walker was killed, dying instantly when he was struck with shrapnel in the Battle of Aubers Ridge.

He was a stretcher bearer attached to ‘A’ Company of the 1/5 Battalion West Riding Regiment.
