This is a cover of a Tom Waits song, which originally featured on his 1999 Mule Variations album. It's not the first time that Stewart has recorded one of the American Rock musician's tunes. "I don't know what it is about Tom Waits that suits me," he told The Sun." "'Downtown Train' was a hit for me in 1989 and that was one of his too. I've never ever met him either! And I've loved 'Picture In A Frame' for a long time. So does (Rod's wife) Penny. "And I've always done and am known for my covers. It's very gratifying and satisfying to do them."
