Personally I actually prefer his voice to hers, I also much preferred their first audition vocally and was disappointed that Mel dwarfed him in the lives.
I don't know where but I read somewhere that she was there because he was supposed to be playing guitar too but he broke his arm?
I want them to do well, however their closeness is sweet but verging on icky, the hand holding and the deep looks - the looks of love I get but it's almost a look of longing.
Still nice voices though!
