"It explores issues that we still face today. Issues like war and conscription, equal rights for same sex couples and for people of different races and genders," he said.
Mr Marshall hoped the musical, which also featured a live band, would have audiences up and dancing in the aisles.
"It's got some fantastic music with great ballads and plenty of tunes people can dance to."
Mr Marshall said the show also featured a colourful set, dazzling costumes, bright lights and a cast of "incredibly talented" performers who were ready to show audiences what they've got.
"It's not to be missed. Get in quick for tickets because they're sure to be snapped up fast."
