I thought she did a good job on it!
I was curious to see how she would perform it, with her full band no less, and I have to say I like the live version. I also liked the way the stage was decorated, and the fact that she was dressed like she is in the video.
I probably shouldn't go there, but I think those fans who don't care for Jim aren't gonna like that fact that he was playing the piano here. But you can't please everyone, I guess. Notice also that she looked over and smiled at Jim once or twice - I thought it was cute! Probably a knowing smile. Oh, and after all the comments that Jim's mic was too loud during her performance in Vancouver Sunday (which I do agree, it was too loud), I was less aware of his vocals here. Maybe Av and the band got feedback after the Olympic performance? I'm sure we weren't the only ones who noticed.
But, bottom line, thank you Avril, for another great performance! Can't wait to see more!
