The Back To Black hitmaker was found dead at her London home on 23 July, 2011, and teen singer Bromfield, who was the last person to appear on stage alongside Winehouse, is determined to continue the singer's musical legacy.
Bromfield has recorded a new track, named Black Butterfly, in honour of her godmother, and reveals she was inspired during Winehouse's funeral service to pen the song - because a winged insect was perched on mourner Kelly Osbourne's shoulder throughout the ceremony.
She tells Britain's Sunday Mirror, "I want to continue Amy's legacy. It's an awful lot of pressure but it's also a massive compliment to think that I can. I was the last person she was with on stage and automatically people felt like that was saying something...
"The song is called Black Butterfly. There was a black butterfly that flew in at Amy's funeral and it landed on Kelly Osbourne's shoulder. It stayed there for the whole service then flew out as soon as the service had finished. It's probably the best song I've ever written and I was crying when I recorded it."
