It’s not too shabby, but the final Beatles song will always be I Me Mine. 😛
But on a side note, what’s with the metallic sound to Lennon’s voice that can be heard on almost every posthumous anthology release? Free as a Bird and Real Love have the same anomaly.
Lennon was always trying out different vocal effects because he didn’t like the sound of his own voice. Using effects on his recordings may be a way of honoring that after death.
But also, these are all vocals taken from demos done at home on cassette tapes, not in the studio with professional-grade microphones & other equipment. I suspect that’s the real reason for the tinny sound; cassette tapes aren’t great.
