The Network, once again, used Silk to introduce
wheras NI used the short cut version of the 2011 Christmas ident with the choir singing
'Ring Christmas Bells'
I think Network have judged this one right on this occasion.
The short 2011 edit you refer to, which is probably an NI exclusive, is arguably the best re-edit of the lot though; the absence of sound effects isn't as jarring from its advanced starting point, with the 2 already in place.
