But on stage, the Rock Tenors look and sound just like any other hardcore rockers who enjoy smashing up hotel rooms, abusing paparazzi and, of course, sex, drugs and alcohol.
DKCM managing director and Rock Tenors producer Doug Kamo said it was one of the major attractions of the group.
And now, after a successful South Island tour, The Rock Tenors are heading back out on the road — this time for a nationwide, 22-concert tour, from Whangārei to Invercargill.
The Rock Tenors formed in Dunedin in 2022 after Covid-19 forced Musical Theatre Dunedin to cancel its production of the Queen musical We Will Rock You.
Five male vocalists from the production were looking for another singing opportunity.
So Mr Kamo took the initiative and assembled the performers for a concert in the city, featuring "high-voltage renditions of rock’s greatest hits".
It was so successful, he took the show on tour around the South Island in 2023.
"We knew that we had a really strong following here in Dunedin, but we wanted to test the waters to see if the concept, the brand, and if the boys would be well-received in other regions.
"We did 10 venues, including Dunedin, and of the nine venues outside of Dunedin, seven of those venues sold out.
"So, coming back off that tour, I thought there’s something in this."
It was also a great opportunity to show the country some of the fantastic talent coming out of Dunedin.
The national touring ensemble includes James Adams, Luke Butson, Ben Hayward, Steve Jones and Justin Wilson — vocalists who have appeared nationally in hit musicals including We Will Rock You, Jersey Boys, Grease (The Arena Spectacular), Phantom of the Opera, Wicked, Les Miserables, Miss Saigon and Mamma Mia.
They will perform signature renditions of rock’s most legendary anthems from Queen, Bon Jovi, Aerosmith, AC/DC, Black Sabbath, Iron Maiden, White Snake, Kiss, Toto, Guns’N’Roses, Red Hot Chilli Peppers, The Animals, U2, Radiohead and many more.
"This is more than a concert. It’s an electrifying rock spectacle, a high-energy blend of powerful harmonies, scorching guitar solos, and timeless anthems that have shaped generations."
While "the lads" would look and sound like rock stars, Mr Kamo said they would not be living the typical rock star lifestyle while on tour.
"We have a pretty strict process that the boys go through on a day-to-day basis, and one of their core focuses across the entire tour last time was vocal health.
"It’s a massive thing to be up on stage for almost two hours, doing rock anthem after rock anthem.
"So, the boys are into a pretty full-on physical exercise programme now as a group, and they are also very careful to look after their voices.
"It was funny coming off the last tour because we were sitting down on the final night and one of the lads said, ‘Well, it wasn’t exactly the rock and roll tour I thought it was going to be — it’s all camomile tea and gingernuts."
Tickets are now on sale.
