As much respect as I might have for Chris Bianco, I don't think he can coax a great pizza out of Jamie Oliver. This forum has some incredibly talented English pizzamakers, but when you get into celebrity English chefs, there's a gargantuan disconnect with pizza. Their definition of pizza is so adulterated, so off the mark, that even help from Chris Bianco can't save them.
Look at Blumenthal's (and by extension, Chris Young's) pizzas. A Michelin three star chef and he makes some of the worst pizzas I've ever seen.
