In her memoir Frankly, the SNP MSP told of nightclub days as a law student at Glasgow University.
She tells how she was shy and introverted when she first arrived at uni and lacked confidence and had a miserable time at first.

She mentioned how, as a young aspiring lawyer, she met two women, Caroline Summers and Claire Mitchell, who became her lifelong friends and who were much more socially active.
Sturgeon wrote: “They were also both much cooler than me and would encourage me to experience some of the social parts of uni life that would otherwise have passed me by.”
In a chapter about combining her studies with her growing interest in the SNP and politics she recounts her time at the Glasgow University Student Nationalists Association.
She tells of frequenting some of Glasgow’s nightclubs at the time. “Fury Mury’s being the favourite.”

Of the crowd she was mixing with, she said: “One of those in the law-student nightclub scene was a guy in the year above us called Gerry Butler.
“Caroline knew him from Paisley, where he also came from, which put us into his orbit.”
While others may not have been aware that Sturgeon would go on to become a dominant force in Scottish politics, she said this student was set for a different life.
She added: “He was always the life and soul of the party, the centre of attention and seemed destined to live a life less ordinary – these days he is better known as Gerard Butler, the Hollywood actor.”
