This is no great surprise, but the choice of replacement is completely wrong.
You don’t get a camp parodist to front a camp parody. You get someone who is the complete opposite, and who is therefore able to essay some ‘ill-at-ease’ business. You also need someone who treats the thing as a television event rather than a song contest, which Norton won’t. Because despite the ever-present ‘songs are so bad they’re good’ constituency, the fact is the songs in the Eurovision Song Contest really are bad (yes they are), and the only reason so many people watch it is precisely because it is one of the few telly ‘events’ there are left.
Someone like Chris Tarrant or Huw Edwards would have been a twenty times more sensible appointment.
