Chicco - he just isn't good enough for a ballad and can't distract everyone with his dancing/stripping!
The Conways - Not a well enough known song and they just aren't working, always looking and soubding miserable.
BUT it could also be any of:
Nicholas, he's yet to impress me and I don't think this song is a very exciting choice.
Andy - I LOVE his voice but he's better at slower, more emotional stuff, this won't make me all tingly!!
Maria - Really rotten choice of song for her. She's not a rock chick. I suppose they're trying to make her different from Brenda.
I feel very sorry for Andy and Maria and hope I'm wrong, I would not have expected them to be in the bottom two for a while yet!
Still, keeps it interesting though, doesn't it? It depends how they all cope on the night.
