Lena Dunham Performs Sia's "Chandelier" (With Sia?)

Sia's extraordinary brilliance crosses over into performance as well, as exemplified in her recent string of performances for Song of Summer contender "Chandelier." The notoriously press- ambivalent Aussie powerhouse has enlisted the help of her peers in various performances of the single. The latest, for Late Night with Seth Meyers, taps Girls creator and star Lena Dunham for a powerful interpretative dance peppered with some trademark quirk. Sia herself doesn't fail to make a stage appearance, however; the audience quickly notices what appears to be the singer laying face down on the bunk bed, singing in real time to the backing track. 

Sia says she'll continue to tap fellow artists around the world to perform the song with her. Who do you hope to see perform "Chandelier" next?
