I do NOT own any of this, I just sang this song for fun. The composer is Wolfgang Amadeus Mozart, of course. Swingle Singers Series arrangement. We sang this at my university, and I loved it so much I felt like attempting to multitrack it.This was the most difficult song I have multitracked yet, but it was so worth it; now hearing the result! :] Every voice you hear is my own, I did not use a pitch shifter this time, whew! I hope you enjoy it, please share with all of your friends and family, thank you so much!
