Watched on TV also, sorry to join the **** club but I'm a fair distance away and Christmas is Sunday =)
So, without over stepping the mark given a full house of blues have paid their hard earned to be there...
Scousers you heard when they scored on both occassions and for the 10 minutes or so following. They were very loud at those points and it actually got me thinking the whole concern about roof sound dynamics etc is a bit of a myth. The stadium can be really really loud if it needs to be, and I genuinely thought they were specifically at those points.
As for blues, could hear singing more often from the home end but most of it was quieter sounding than the few times the scousers sang, if that makes sense. Any chant seemed to be over fairly quickly and perhaps just never got the whole crowd singing at the same time which dulls it down a bit.
