Susan Boyle is transformed when she sings, she has a lovely expressive face. Her voice is beautiful but seeing her sing adds to the experience. There are people who have 'faces for radio' who still do very well in the music industry because it is about so much more than just looks, the Proclaimers spring to mind but I am sure there are many other examples. By the way I would much rather not look at Simon Cowell's face!!
