The third annual Amy Winehouse Foundation Ball will be held at the Dorchester Hotel tonight.
The Foundation runs a scheme called Amy's Yard, where young people referred to them by partner organisations are given professional music studio time and the help of a professional engineer to develop both music skills, plus social skills and self confidence.
Four young people from the scheme will be performing at the event to showcase their talent alongside musicians including Boy George and Paloma Faith.
A host of music stars turned out tonight to raise money for disadvantaged young people, in memory of Amy Winehouse.
Family and friends of the late singer attended a ball at The Dorchester hotel in central London, held by the Amy Winehouse Foundation.
It was the first major fundraiser for the charity, which was set up following the singer's death to help young people struggling with homelessness, drug abuse and alcohol problems.
Speaking at the event, Amy's father Mitch Winehouse said early intervention was key to preventing young people falling into substance abuse.
He said: "We need to do as much as we can to raise as much money as we can for disadvantaged young people.
"The key is early intervention, which means getting into schools and speaking to young people at the earliest opportunity. Giving them all the information they need and allowing them to make the appropriate decisions for them.
"It's not going to help everybody. There's still going to be people who still turn to drugs.
"But if people know that legal highs might be legal but they're not safe, they are not stupid, they'll be able to make the appropriate decisions for themselves."
Tyler James, who found fame on BBC One talent contest The Voice, was living with the troubled star when she died of drink abuse.
He said his performance at the ball was in memory of Amy, who he called his "soul mate".
"I had alcohol problems in the past, I went to rehab, I'm lucky to be here. I was taught quite a lot about drugs in school, but no-one really talked about the dangers of alcohol," he said.
"I'm still grieving but something like this helps me because it's a really positive thing. She'd be so proud of her dad and her family."
Mark Ronson, who produced Winehouse's award-winning Back To Black album, said: "I'm here to support the foundation and to make sure money is raised to let Amy's legacy do some good."
