Nah, the last season Grant hosted was the one that spoiled it. New Host Tom was an effort to revive it but it'd lost its appeal by then.
He's an odd choice though. Guess he was still under contract?
The new series in the US was a lot of fun, at least the episodes of it that I saw. I was sort of expecting crazy levels of safety gear being required, but it's still pretty mental. Hopefully the Australian one follows suit!
