Emily McGonagle was watching cartoons with her sons when she decided to embark on a career change. A decade on, she is a star of a globally popular children’s series

Emily McGonagle was on maternity leave from her job as a lawyer, juggling the care of her new baby and her toddler son, when the daily diet of TV cartoons made her think about an unlikely career change.

Watching Peppa Pig and Paw Patrol, her older son’s favourites, “it occurred to me: who does this job?”, says the 42-year-old from Essex. “How do you get into it? Even when I was watching TV commercials, I’d think: well, how do you do that?”

When 17-year-0ld Danny Donelly got a bank loan to open a record shop and sell dancefloor-filling electronic music, he little knew how he would help revolutionise his town and dance music at large

In the early 1990s, the suburban town of Romford was known for three things. It was the home of the world’s best snooker player, Steve Davis. It was where people placed bets at Romford dog track, over a dinner of chicken in a basket. And for those in the know, it was where the UK’s best underground dance music was bought and sold.

That pedigree was immortalised by Romford’s most famous musical act, Underworld, with frontman Karl Hyde shouting the words “mega mega mega, going back to Romford” at the climax of 1995’s Born Slippy. Those words now form the title of a new exhibition in the town, Mega Mega: Romford’s Suburban Sound Revolution, which charts how this unglamorous but party-spirited backwater became an upstart rival to great dance music cities such as Manchester or Detroit.
