But then Glasgow sometimes produces the entirely unexpected, and Frances Thorburn is a case in point.
Growing up on the South Side, Frances discovered a real passion for singing. But rather than follow her friends' lead and try to copy Madonna or Whitney, Frances was far more interested in Ella Fitzgerald's phrasing.
"I grew up listening to Ella and Billie Holiday,which is surprising given my dad was a huge Queen fan," she says, smiling.
"But I just love the jazz era. I think I've got an old music head on young shoulders."
Frances's passion for jazz and acting has paid off. She is currently appearing in the The Jazz Club Murder, the latest Oran Mor play in which her central character is Gloria Dee, a singer in a Soho nightclub.
At the Black Cat club a murder takes place and this musical whodunnit reveals an array of characters, including gangsters, jewel thieves, and amateur tec Sidney Chambers, who tries to solve the murder.
Each of the actors - Frances, George Drennan, Paul Dodds and Danny Boyd - get to play several characters.
Frances plays an American and a posh English lady. But how did her love of jazz develop into performing the music?
"When I was at school in Eastwood I appeared in South Pacific, and the trumpeter, Martin Coogan, then in his thirties, was a guest performer," she explains.
"He heard me sing and asked me to do a charity concert at the City Halls. From there, he offered me the chance to join a jazz band.
"Suddenly, at 15, I was in a world of old jazzers and trumpeters with elastic cheeks and I just loved it.
"I was studying for my Highers and playing with an eight-piece band at the same time."
Frances cut her music teeth in the likes of the Cool Jade restaurant in Carmunnock, singing I've Got You Under My Skin.
But then the dilemma kicked in; Frances had also developed a love for acting.
"I couldn't make up mind whether to go to drama college or music college to study piano. And because I'd been gigging, I didn't want to become a classical singer or a concert pianist so I joined RSAMD.
"Luckily, now things weave into each other. And it's great to have several strings to your bow. You can't rely on one discipline these days."
Frances, worked in London for six years, appearing in Fiddler On The Roof at the Savoy Theatre and enjoying stints at the likes of the Globe Theatre with Anthony and Cleopatra.
Back in Glasgow, she has appeared in Glasgow Girls and starred as Monroe in Marilyn, both at the Citizens Theatre.
Frances has also appeared in River City as politician's wife Hannah Morrison, alongside screen hubby Colin McCredie.
But her music life still thrives. Frances is also a songwriter and is working on a new album (jazz of course).
And she performs in Glasgow restaurants and clubs such as Guys, on Candleriggs, on Thursday and Saturday nights.
"I feel I'm quite successful, yet still struggling," she admits. "I'd love to see more opportunities to appear in Scotland."
She adds, smiling: "I'd also like think about having a family and things like that. My boyfriend is a drummer, who's with the Red Hot Chilli Pipers in China right now, and I've just bought a new phone so I can Facetime him."
Frances adds, laughing; "What's great is he's a performer, but not an actor. I think one actor in a relationship is enough."
