Winehouse’s friend Russell Brand led the eulogies, asking people to remember the singer for her music and urging those suffering from addiction to get help.
The comedian, who has battled drug dependency himself, said: “A lot of people just get the disease, not many people get the incredible talent that Amy was blessed with. Let’s remember there is a solution. That solution is available.”
Winehouse was also mourned by British artists such as Jessie J and Adele, both former students at the BRIT School for Performing Arts and Technology that the “Queen of Camden” attended.
Speaking ahead of the show, Jessie said the pair were still struggling to accept Winehouse’s death.
She said: “It hasn’t sunk in yet, really.
“I’ve always said that me and Adele, and a lot of the British female artists, were able to do what we do because of Amy.
“I will not let her down. I will work my butt off until I hopefully achieve what she did.”
Adele applauded Bruno Mars’ take on Valerie, the Zutons song made famous by Winehouse and Mark Ronson. Mars finished with the line “Amy, we’ll miss you baby”.
Legendary crooner Tony Bennett showed the audience a clip of the Body And Soul duet he recorded with Winehouse before she died last month.
The single and video featuring the pair will be released on September 14, which would have been Winehouse’s 28th birthday.
