First one: I respect her ability to hold a note that high. But, just... I couldn't stop laughing at her, she just, her voice kept wiggling toward the end of the verse! XD Also, you know you suck when Simon nearly snorts in laughter. I mean come on, she kept blinking so weird and moving her head in a circle!
Second: They weren't too bad, I like how they were able to keep the same exact note with each other. But yes, they did look like a pair of corpses. O_o
Third: ... I really have no idea what to say, I'm just out of words for this particular woman. O_o She's a little obsessed with dentistry it seems...
Four: Sing in time with each other! For god's sake, it would sound better if it really WAS just a faint echo on a track, but live and in person that manner of stagework just sucks.
Five: Just, leave. Quietly. And carry no sticks, as I'm sure the police will arrest you.
Six: Why do I get the feeling they planned the crying face bit? I mean, she was crying before the song was over!
