Grange Hill had passed its peak by the Nineties but limped into the Noughties, when it relocated to Phil Redmond’s native Liverpool, where the set is now used for Hollyoaks High in his other youth soap. The BBC eventually admitted defeat and pulled the plug in 2008.

Tucker Jenkins (played by Todd Carty) returned for the final episode, persuading his nephew Togger to stay on at school for another year. “If it hadn’t been for this place, I’d have been written off,” said Tucker. “You can be anything you want to be. Every year is a fresh start. Grange Hill is for everyone.”

Now, 44 years since the bell first rang in February 1978, it’s heading back to our screens. The original show provided early TV exposure for some future stars, while others sank into obscurity – or, in some sad cases, tragedy. Here’s a school reunion…

SUSAN TULLY

Was: Rebellious Suzanne Ross, who broke the rules, left school early and memorably dressed up as Boy George for the school disco.

Now: Tully moved across London to become one of the original EastEnders cast, playing Michelle Fowler – who married Lofty and had Dirty Den’s lovechild. She’s since moved behind the camera, becoming a respected TV director on the likes of Line Of Duty, Strike, Silent Witness, The A Word, Britannia, Too Close and Tin Star.

LEE MACDONALD

Was: Zammo McGuire, whose descent into heroin addiction strained his relationship with loyal girlfriend Jackie and inspired the famed “Just Say No” anti-drugs campaign.

Now: Macdonald appeared in The Bill and Birds Of A Feather, before becoming a champion amateur boxer. He now runs a locksmiths in Surrey but in 2019, now aged 50, he popped up in EastEnders as a bus driver called Terry who squabbled with Queen Vic landlord Mick Carter (Danny Dyer) over some Spice girls tickets. As you do.
