I've read somewhere (Ned Boulting's yellow jumper book?) that the pair of them are actually doing simultaneous coverage for UK, Australian and US channels. So while one of them is babbling specific stuff for a British audience, the other one may be giving the Aussie audience something tailored to them. That could explain the repeats. Although Phil did seem to fluff his lines (particularly names) more than usual.Liggett certainly is, the amount of times he repeated what Sherwen said as if Sherwen hadn't just said it was dumbfounding.
