Acoustic/Slower Version of You Are the Best Thing

Does anybody know where to get a copy of the acoustic / slower version of 'You are the Best Thing' song that Ray has been singing at his concerts lately? He stated that he originally intended to record this version, but it didn't quite fit on their album so they jazzed it up a bit. I would love, love, love to use the acoustic version of the song as my first dance at my wedding. I've found some videos online of live preformances of the song, but there is a lot of talking/clapping or other noises that make it impossible to use at a wedding. Anyone know?
