flawless?? yah.. i've watched their performance in you tube for the semi-finals and they are great.. but, i think Miss Susan Boyle is leading??? great performance from the show.
I really like Susan Boyle. The judges and even the audiences didn't acknowledge her as a singer/performer. But once Susan started her singing, the audiences are shocked and they can't believe what they are hearing. I really like this kind of situation when single person proves his/her worth in the right time.
