Libertines front-man Pete Doherty has unveiled his tribute song for Amy Winehouse, and proceeds from the single will go to the Amy Winehouse Foundation, which aims to help young people understand substance abuse.

Here a sample of the lyrics from Flags Of The Old Regime:

the fame they stoned you with

your tiny shoulders soldiered it

and you made your fortune but

you stumbled, broke inside

you had to stand up there in front of the whole world

and you don't feel them songs no more

Whatever you've heard about Pete Doherty, this song is as tender and poignant a ballad as one could ask for. If you've lost a friend to drugs, or you miss Amy like I do, have a listen now.
