Amy Winehouse had all of her third album written before her death in July.

Winehouse was in no hurry to release the material. Instead she hoped to release a jazz album with a supergroup, that was to include The Roots member, ?uestlove. There were many other contributors rumoured to be involved, including the saxophone player Soweto Kinch.

Only two of these songs were recorded and will feature on her upcoming album, 'Lioness: Hidden Treasures'. 

?uestlove is set to feature on one track on the album, called 'Half Time'.

The last recording the 27-year-old committed to tape was a duet with Tony Bennett, called 'Body and Soul', and was released in September to benefit the Amy Winehouse Foundation.

The album will be released in early December. Listen to the lead single from 'Lioness: Hidden Treasures', 'Like Smoke', and a behind the scenes look at 'Body and Soul' below:
