This years CIN from Northern Ireland is coming from the Kings Hall instead of Blackstaff House. A move I don't think they've done since the Odyssey Arena a good few years ago.
You can tell when a show comes from TC1 they seem to use the same background lights. The sets just look to similar, the Last Choir Standing set looks like the set they use for those pick a star for a musical shows which looks similar to the I'd Do Anything set which looks similar to the National Lottery Awards set which looks similar to the Children In Need set. Compare it to Studio 1 at The London Television Studios , the sets look totally different for each show.
Also they should bring back a sofa area for Terry to present the show from, and they should change the set next year.
