Musician Paul Hardcastle has remixed his  hit song '19' on its 30th anniversary to raise money for troops suffering from Post Traumatic Stress Disorder (PTSD).

The original song, a commentary on the Vietnam war, spent five weeks at number one, and catapulted Mr Hardcastle to national pop fame after recording it in his house in Leytonstone.

The hit composer says he created the new "hard-hitting" music video after sitting down with PTSD victims to get a picture of how they felt.

In the remix soldiers recount their battle experiences in graphic detail.

One soldier says: "You are 18 years old and your wearing someone’s brains down your shirt because they had their head blown off right next to you. And that is not supposed to affect you."

Its powerful anti-war message is based on the average age of a US combat soldier fighting in Vietnam.

Paul Hardcastle’s new album, 19 The 30th Anniversary Mixes has been released today with proceeds going to PTSD charity Talking2Minds.
