This video that Ray already posted is one of my favorites, not because of filmanship, but it caught some very good moments, plus the close up while she's singing in good def, though a little shaky was good to see.
3:25 Alizee first shows up on stage and in this video
3:32 Starts singing
5:13 Get's a great, great smile and sticks tongue out
7:26 She's turning her head left and right repeatedly as if she'd confused by something going on in front of her; then turns her head and another great smile
7:45 This is the one Ske posted a shorter video of this moment already. She's looking at Greg and has this great look on her face as she turns forward. A look of disapproval or whatever to what he said.
