When Michael Parkinson voluntarily took his talk shows off-air, he stayed away for rather more than a decade. Eventually he returned from the wilderness to his natural home on Saturday night and was rightly greeted as the prodigal son of chat. Jonathan Ross has unwillingly been away for a 10th of the time, having left under a storm cloud, but from the wall of squeals which welcomed him back to his regular gig you might have mistaken him for the Second Coming. Either that or those floor managers who encourage the audience to clap like stink are on double pay.
