I recently found an old audio file of me vocalizing some of the sections from The Boy's SMiLE album. I just had to finish it because I had some good ideas on how to sing some parts. I pretty much try to sing the instruments and duplicate the vocals as well as I can. Some parts I included originally, but most vocals are from the SMiLE album. So enjoy!
