Infectious, memorable and sometimes downright annoying - they're the kind of "songs" that get stuck in our brains and, for entire generations, can prompt a walk down memory lane.
We're not talking about Number One tunes or retro hits, but advertising jingles that have you back in the living room of your childhood home before you can even say "utter peanut butter nutter". Just ask Dean Hewison, a commercials director, theatre and film-maker who frequently found himself humming ditties from the catchiest ad campaigns of the 1980s and 90s.
"I'd had these ads in my head since I was a kid watching too much television," he says, adding the lament of pre-internet generations, "because there wasn't much else to do back then but watch TV."
Rather than keep the retro jingles in his head to hum at traffic lights or in other idle moments, Hewison decided to seize an opportunity to strike theatre gold. With help from musical director Amand Gerbault-Gaylor, he pulled around 20 jingles together to craft a musical comedy premised around one of the oldest storylines in theatre: small town girl leaves sleepy country home to make it big in the city.
