A track on Amy Winehouse's new album heavily samples a song from The Wizard of Oz, it's been reported.

Winehouse has apparently become obsessed with the 1939 musical, which starred Judy Garland.

And according to a report in the Sun newspaper, the singer has sampled the 'Wicked Witch of the West' in a new track.

“She loves the surreal look, sound and score. One of her new songs heavily samples the theme tune,” a source told the newspaper.

“And the soundtrack and score will be a theme running throughout the record.”

The unnamed source described the song as “really interesting, if a little bizarre," adding: "I suppose that’s what you would expect from her at the moment.”

It's not yet clear when Winehouse – who was criticised for her performance at last weekend's V Festival – plans to release her third album.
