When I had Harley, Martin was busy working and I thought, ‘You can’t have two parents doing that work.

My daughter not only wrote two songs, but she photographed us for the album cover, she made all the video and she filmed the whole making of the album," Shirlie reveals.It'd mean more if he plays us on the radio though," quips ex-EastEnders star Martin, referring to their son's job as a Capital FM host. Roman didn’t plan on being a DJ but, when Capital came along, I said, ‘This is a better path for you’, and he really excels at that. Being a DJ is the most euphoric feeling – to have 1,000 people in front of you all singing every word to the best 80s words. For Martin Kemp and his wife Shirlie, recording a Swing album together has been as much of a surprise to them as it will no doubt be to their fans.

Well the kids are all grown up now and I’m so pleased that we have waited and are able to do it now. We didn’t have a big wedding, but seeing all those people working on our project, I felt overwhelmed. Harley Kemp’s songs Like We Used To and When We’re Apart are impressively faithful to the era’s spirit, as Martin says: “It was the first time we’d heard Harley’s take on her mum and dad’s marriage, and that was so touching. Alongside classic tracks including ‘Nice Work if You Can Get It’, ‘Ain’t That a Kick in the Head’ and ‘The Way You Look Tonight’, the album features two original tracks written by Martin and Shirley’s daughter, Harleymoon.Part of the secret why we’ve lasted is to make sure you look after your friendship as well as your love for each other. The plate is unnoticeable but not undetectable; during an appearance on the Frank Skinner Show in 2002, Kemp jokingly remarked he could never slip quietly through metal-detectors at airports, as the plate would set the alarm off. I just couldn’t understand the concept, but I was there because George wanted someone he could trust.
