Sia performed “Bird Set Free” on Jimmy Kimmel Live last night (March 14) via the Samsung Galaxy Life Fest stage at SXSW.

Accompanied by a lone stage dancer, Sia graciously belted the liberating lyrics to the standing room only crowd, “And I don’t care if I sing off key, I find myself in my melodies, I sing for love, I sing for me, I shout it out like a bird set free.”

Sia originally pitched “Bird Set Free” to Rihanna, who passed on it, then to Adele, who initially recorded it but later decided to let the wigged enigma keep it for her album. Watch the performance below and buy Sia’s This Is Acting available on iTunes now.
