I'm also really happy with what I have seen of Chico tonight. It's a big change of direction, but if he can pull it off, and I don't see any reason at this juncture to why he can't, he could really throw the whole voting system into confusion.
What makes the difference, from the clips they showed, is the way he portrays the tune. He doesn't just sing it, he puts emotion and feeling into it, which is what has been lacking in some of the other contestants offerings thus far.
I'm keeping everything crossed that he does well and, please, please, has positive critique from the judges. I shall be really saddened if they put him down for changing his musical style.
One thing I do know, if his vocals are good on the song on Saturday night, it will be worrying for everyone else if he gets back in for another week, because with the personality and humour he has already shown, he really is beginning to look as if he DOES have the X-Factor! :0)
