I recorded myself FCing the lead (blue) vocals and set it to play from the left speaker. I then FCed the first harmony (orange) vocal part and set it to play from the right speaker. I then synchronized the two parts, put microphones to the speakers and played it back in sync with the game. As my recordings played back, I used a third mic to sing the second harmony (brown) part "live." I did NOT keep the recordings so I will NOT be posting them for others to use.
