British soul singer Amy Winehouse is remembered by celebrity friends and family.
The event was held for the foundation set up in the late singer's name after the Grammy award winning singer songwriter died of alcohol poisoning in July 2011.
Her father Mitch said more work still needed to be done on helping people like his daughter.
SOUNDBITE: Amy Winehouse's father, Mitch Winehouse, saying (English):
"People don't understand addiction. I didn't understand addiction. You know, I thought that by shouting at Amy going, 'Why? What are you doing? You can stop taking drugs, you can stop drinking.' That's not a clever way of dealing with this stuff. So, in answer to your question, I don't think anyone is more susceptible to it than anyone else. I don't think there's an addictive personality, per se. But I think it's more about education."
The foundation was set up to educate young people about drugs and alcohol, and provides support for the most vulnerable.
