McGrath trained in IT at Thames Valley University in 1989, largely to appease her parents. After landing a job, she quickly realised that the profession wasn’t for her. “I didn’t really know the reality of the job,” she tells us. “It was only when I retrained to work in education that I realised I love entertaining people. But I didn’t grow up feeling that comedy was my calling. It happened by chance.” Her new show, Breaking Black, opened at the Edinburgh Comedy Festival on August 3.
