Ok, I guess the show was live. If so, good job by the production team. Having everything and everyone in place for each performance isn't easy, even if they were simple setups. This is a lot more than they used to do, and it also points up another WEAKNESS with this show. It used to be that the contestants were on their own to work up an audience. Now they are receiving a lot of help in that regard. Less attention on the actual singing/personality of the singer, more walking through doors. It's more manipulation by Nigel, and I expect we'll eventually hear singers complain about favoritism toward certain singers.
And then there are those trio performances, which is a big mistake. The only reason they are doing it is that they have that extra time to fill in the 2 hour time slot, and they can only fill it with so much boring fashion advice. The big problem is that people will vote on how a singer does in these performances. There is no way to separate them from the "official" performance when they are done the same night. I have a feeling that few people remember Holly's song, and a lot more remember Holly's off key rendition of Madonna that occurred later in the show, closer to voting time. Holly might be in trouble this week.
