Paul Hardcastle spoke to his son just minutes before his death in a motorcycle accident.

The 68-year-old musician - whose track 19 topped the UK Singles Chart in 1985 - revealed on social media earlier this week that his son Paul Jr, 35, had tragically passed away in the incident and has now explained that the pair spoke on the phone in the moments prior to the fatal accident.

Paul said in an Instagram video: "He went like, 'I'll get back to you in five minutes.' He didn't get back to me in five minutes."

The 1980s music star also discussed the moment police officers knocked on his door to inform him of the awful news.

An emotional Paul said: "I've lost a lovely son, and he's lost his life, and it could easily have all been avoided.

"But that's decisions. You make decisions, and if you make the wrong ones, then these are the things that can happen to you. So anyone out there that's thinking, 'Oh, I'll just do this. I'll just do that.' It's just not worth it.

"Because when you get that knock on the door, and I felt sorry for the policemen, actually, there's two of them and they was nice. And they said, 'Do you mind if we come in? We've got some news.'

"I said, 'Okay.' (They replied) we're very, we're very, very, very sorry to tell you that your son's been involved in an accident and he's passed away."

Hardcastle continued: "When you hear that, wow, nothing's worth doing it for.

"So anyone out there thinking along them lines, don't bother. It's just not worth it. Cancel the gig. Do something else. I don't know whatever you want to do, but don't do that, because it's really that the odds, I won't say the odds are set against you, but the odds, when they come up, then they can be really brutal, and that's what happened.

"So rest in peace Paul Jr, love dad."

Paul had revealed the sad news of his son's passing with a brief message on Instagram accompanying a childhood photo of Paul Jr, who had followed his father into music by playing the saxophone and DJing.

He wrote on the social media platform: "Just to let you know that my super talented son Paul Hardcastle Jnr was in a fatal motorcycle accident earlier and has sadly died. RIP son love Dad."
