The City of Wolverhampton Orpheus Male Voice Choir, which was formed in 1943, performed a medley of songs for two-and-a-half hours under the shopping centre's dome.
At present, the choir has 23 members divided into four sections; first tenors, second tenors, baritones and basses.
Of the event on Saturday, vice chairman and concert secretary Steve Winfield said: "It went great, we put out loads of recruiting cards and it's now just a matter of seeing the response.
"It went really well, we did about two-and-a-half hours and we are looking to do another one in the next few months, possibly in the Mander Centre."
The City of Wolverhampton Orpheus is a registered charity and members sing to raise funds for a number of causes, including Midlands Air Ambulance and The Royal British Legion.
The choir also regularly performs at churches in the area, for weddings and funeral services, and visit residential homes.
Mr Winfield has been involved since the mid-1980s and spoke of how difficult it can be to bring in new recruits.
"I started in 1986, carried on until about 1992, and then took it up again around 10 years ago," he added.
"I still have a great passion for it but it's very hard to get people interested, especially those in their 20s and 30s.
"When I started, we were 45 strong and a lot of the members have been involved for many years.
"We are doing more new pieces now, a lot of songs from musicals.
"We are looking for lower section – basses and baritones – and we had good support in the Wulfrun so we are hoping to build on what we have got."
The choir rehearse every Wednesday between 7.30pm and 9pm at St John's Church, Wolverhampton Road East, Parkfields.
The choir will be singing for the Battle of Britain church service on Sunday September 18, which is at 4pm at St John's in the Square.
