Gwion seems very nasal when he sings & I thought he was amongst the weakest of the boys. There was another boy with wide eyes and slightly gappy teeth if they wanted to go for the cute factor. Agree with TTT that Jordan should have been chosen; thought he really drew the eye and could sing.
Thought Rachel was fabulous but needs to contain her jealousy and open ambition; the viewing public don't like to see it, especially in a woman.
The buxom barmaid and Sam ought to go through too. Although Jessie can sing I can't bear to watch her - the sneer and her awkward movements are very uncomfortable.
