Unreleased songs by Amy Winehouse will form part of a memorial album to be released this winter.

Island Records said the posthumous collection would feature 12 tracks, including Body & Soul, the song she recorded with Tony Bennett just weeks before she died last summer.

The album – the third under Ms Winehouse's name - will also include a slower version of her hit cover of the Zutons' song Valerie and new songs called Halftime and Between the Cheats.

Her father, Mitch Winehouse, said the new material was "incredibly beautiful."

"If the family had felt that this album wasn't up to the standard of Frank and Back To Black we would never have agreed to release it," he said. "We believe it will stand as a fitting tribute to Amy's musical legacy."

The album has been compiled with the help of the Winehouse family and the singer's friends and musical partners Mark Ronson and Salaam Remi.

Some of the profits will go towards the Amy Winehouse Foundation , established after her death to support disadvantaged young people.
