<p> "Defying Gravity" is the main song from the musical Wicked, composed by Stephen Schwartz, originally recorded by Idina Menzel and Kristin Chenoweth on November 10, 2003, and released on December 16, 2003. It is mostly a solo sung by the main character of the show, Elphaba (the Wicked Witch of the West), with two small duets at the beginning and in the middle of the song between Elphaba and her friend Glinda, and a chorus part in the end in which the citizens of Oz sing. It was performed on the BBC television programme I'd Do Anything, and as a result the song charted at no. 60 on the official UK Singles chart.
