Christina Aguilera performed another song from the Burlesque soundtrack, Bound to You, on the Tonight Show With Jay Leno.
The beginning, with its lower tessitura, sounded comfortable and in keeping with the recorded version of the beautiful ballad. However, as the song hit its middle-eight and the higher belted notes began, it started to sound pretty shaky, with some of the top notes sounding out of tune and strained.
Overall it wasn't the most pleasant vocal to listen to. Hopefully it's not a reflection of the stress of the breakup and poor album sales affecting her.
