That whole [Abbey Road] album takes you for a ride. And I Want You (She’s So Heavy) takes you for a ride within that ride. Those monster riffs seem to go on forever and then suddenly drop you off a cliff. Lennon’s vocals are just so passionate. He hated his voice, as Hendrix hated his. I think the fact that they weren’t typical singers made them even more expressive. A lot of trained singers have less impact than someone who’s just flying by the seat of his or her pants.
