This was done by isolating the vocal track from the Rock Band .mogg file and using mvsep.com's "MDX B (Karaoke)" model to take out Paul's lead vocal, though a trace of it can be heard at 0:12 (it sounds like a robot lol). After downloading it, I used Vegas Pro's "Noise Gate" effect to take out the mic leakage of Paul's vocal.
Backing vocals sung by John Lennon, Paul McCartney, George Harrison
