The group of 30 singers was formed by Oamaru Sings, comprising song leaders Sally Randall and accompanist Rick Loos, with technician and "That Food Guy" Mark Townsend and teacher Amanda Dennis.
Oamaru Sings was established last year and was given funding from the Waitaki District Council Creative Communities Scheme for their first community singing project.
Community song leader Ms Randall said the singing group was inclusive and was made up of singers of all different ages, backgrounds and abilities.
"It’s not formal, there’s no pressure. It’s just about the joy of singing ... and bringing everybody together to sing, including the audience."
She said the group will perform a series of songs and "show off their vocal skills" at the Scottish Hall on July 21, after 10 weeks of rehearsal.
Ms Randall, whose background is in nursing, psychiatry and naturopathy, said spreading the joy of singing was her main purpose these days.
"When people come together in a group to sing together — and that would include the audience when they come in and they sing with us — it’s an amazing connection that happens. When people sing together, it lifts people up and people carry that right through, sometimes for days, after that experience.
"It’s about helping people feel good. There are many, many, many benefits, physical, psychological, spiritual, all sorts."
The All Together Now singers will perform 13 songs, with Mr Loos accompanying on guitar.
They have also planned audience participation songs to beat the winter blues.
"[It’s] mostly uplifting, because it’s winter and we want to have a good feeling.
"There will be easy things, and there will be fun things. "
The original concept for the show was to include youth and other community singing groups, but Ms Randall said for different reasons the groups have had to withdraw.
"The Limetones didn’t have sufficient numbers and then the library has a group called the Community Waiata Group who were going to perform, but they withdrew. Now the Waitaki Girls’ choir pulled out because of sickness."
Despite the changes, Ms Randall remained optimistic about the show.
"We’ll just have longer for the community to mingle together over having a shared supper.
"We’re really hoping this will bring people in the community together. I believe it will."
A member of song leaders Network Aotearoa, Ms Randall has been learning the skills of a song leader since 2011.
She said it was all about the tradition of oral singing as opposed to learning with sheet music or having to read music.
"I see myself as a carrier of song, because I don’t use sheet music. I don’t expect anybody to have any experience in anything. I learn a song, I teach that song line by line and then they sing it back to me."
Ms Randall said Oamaru Sings was developing workshop ideas for the future of the group and they plan to keep the original youth concept alive.
"We might do some things for children ... there’s a need for something for the young people."
