I was actually there for the taping of this show. She performed "Fix You" twice, because she didn't like the way it sounded the first time, but I thought she sounded great both times.
I've met her twice before, and in between songs during the taping, she noticed me sitting in the second row (I was probably literally only 20 feet away from her). She stared at me for like 3 seconds and then said "hi!". I was so shocked she actually recognized me, I just waved back lol. She then said something like "I recognize some faces in the crowd..." I was on Cloud 9!
She's such a sweet person when I met her too. She makes eye contact when talking to you, and doesn't make you feel uncomfortable or awkward. Very kind and down to earth. It's like you're talking to a friend. I'm just as big a fan of her as a person, as I am of her as an artist.
