You want to ask how come a smaller show can arrange sound thats audible, a backing band that doesn't drown the singing and why without the Nancy team providing the vocal coach or the choreography or her dress Jessie can get the interpretation right, avoid all the gestures that put anyone off and look far better in her own clothes. Perhaps next time they should bring their own clothes, sack the choreographer and either get some new vocal coaches or allow people to use the people they had advice from before the show.
Louis Walsh likes her........hopefully not as a member of the Girls Aloud replacement band though .
