This wonderful extra is Tom Waits’ very illustrative theme song for Iron Man 2 which was sadly rejected.
Tom Waits, for those unfamiliar, is an very exceptional singer/songwriter/multi-instrumentalist/painter/actor and is also very famous for his particularly distinct gravely voice.
Check out the video embedded below.
Okay, okay, so it’s not really a rejected Tom Waits theme but the work of Adam Buxton who jokingly describes it thusly:
Mysteriously absent from the Iron Man 2 DVD extras; this early attempt at a theme tune was rendered by legendary gravel voiced song barker, Tom Waits. Jon Favreau gave Tom the shoe of a tramp and a rusty euphonium for his trouble, so there was no bad feeling.
