I've just been watching videos of past performances from every series, mostly Guy, and I just will never understand why he didn't repeat his performance of "Climb Every Mountain" in that World Idol show. Did they not want him to win? Of all the songs he did, "What a wonderful world", must be the lamest. He could have sung "I'll be there", "When I get you alone", "Crazy in love", etc. anything else, and he would've blown them all away. No wonder the World Idol didn't get a return performance.
