“We used to wear some mad clothes. I remember coming downstairs with make up on and a robe like Jesus’s,” says Kemp. “My dad was sitting in his chair. I said: ‘I’m just going to the pub.’ He looked over, didn’t even smile and just said: ‘Have you got your keys?’
“I owe so much to mum and dad for giving us that much freedom. I have tried to pass that on to Harley and Roman, but it was easier for me because we were more financially secure.
“Everything when you are 16 is exciting – and if it is not, you want to ask yourself why. It was a super exciting time to be young in London, watching all the punk bands at The Vortex and The Roxy and being involved in that scene.”
On the pop stardom that accompanied his outrageous outfits, Kemp says: “Because of my background as a child actor, I understood that music was a piece of theatre. When I was on stage, I was playing the role of the pin-up. Looking at it like that was key to keeping my feet on the ground.”
I was lucky. I met the right person. I met Shirlie
Kemp describes his upbringing as being a world away from the lifestyle he was able to afford when Spandau Ballet hit the big time. “We had zero money. We had nothing. We were so poor,” he says.
Reflecting on advice he would offer his younger self on matters of the heart, Kemp says: “I was lucky. I met the right person. I met Shirlie.
“And maybe it goes back to my mum and dad again – they showed me how to be a good person, they showed me how to love in the right way, they showed me how to build a relationship. They were together 55 years until they died – and they died three days apart. So their relationship is the one I base mine on.”
The latest twist in a career that has seen him as a pop pin-up, a soap superstar, and a serious actor sees Kemp and brother Gary in BBC2 mockumentary The Kemps: All True.
For Kemp, it was a chance to act with his brother again following their breakout acting performances in The Krays back in 1990.
“I was really lucky to work with Gary on The Krays. Working with my brother was half the job done because we were playing twins,” he says.
“It was nicest way to go back into acting. Both of us leaning on each other. If my first job was on my own, I can imagine it being stressful. Working together was one of the loveliest experiences.
“The Kemps: All True was a lot of improvisation, taking the piss out of each other. The nicest thing for me was that Gary was taking the piss out of himself, which you don’t see that often. I have done it all my life, but for him to do it was really different.”
