Pete Doherty Pays Tribute to Amy Winehouse in ‘Flags of the Old Regime’

It's been nearly four years since Amy Winehouse died, and now Pete Doherty is paying homage to the late singer -- and his friend -- with a new song.

Entitled 'Flags of the Old Regime,' the Libertines frontman wrote a somber ballad that gives fans a sense of his emotions through sound of his scratchy vocals. Proceeds from the track will go to the Amy Winehouse Foundation, an organization set to help young people who've gotten into the misuse of drugs and alcohol.

The track features Drew McConnell of the Babyshambles and Helsinki playing bass, Jamie Morrison taking on the drums, Stephen Large on the keys and Stephen Street on percussion and acoustic guitar. The strings are arranged by John Metcalfe.

'Flags of the Old Regime' will officially be released on March 9, but in the meantime, you can hear the song in its entirety below:
