Take the following news with ‘a grain of salt’ as this is not confirmed at all by The Prodigy.
However over at Noise Creep, they had the following line in their news post about the Worlds on Fire release:
“The DVD also includes a treasure trove of hidden video extras.”
So if this is true, what do you think it is? More of their YouTube clips? Or some demos? Who knows. We’ll just have to wait and see if it’s true anyway.
