I think this is probably my favorite Pink performance/song ever.
P!nk - Glitter In The Air (GRAMMYs on CBS) - YouTube
Yes, that was amazing. That over the rainbow one is right up there for me though. At the end when she smiled at Judy Garland's family, it was like, that was for your mom! Ever since I was a little girl, that song has meant so much to me. Loved Pink's version.
