Tonight... yes, I think so. They were simply the best act.
The competition as a whole... no, not so much. Escala appear to be professional musicians who have released music and worked commercially. While they are admittedly incredibly talented - and gorgeous - and would be a wonderful act to represent the UK, BGT is supposed to be for amateur talent. So I have to say that I will be supporting George to win, because it is acts like him, and Andrew and Faryl, that the show is all about: finding complete unknowns in unexpected places who are barely aware of their own abilities and could never dream of the opportunity for the kind of performances the show allows them to make.
I REALLY hope it is one of those talented kids who walks away with the grand prize.
