Here we have it folks…the Beatles classic that essentially invented the raucous, brutal sounds of what would become Heavy Metal. Apparently inspired by the language of a bullshit review spewing hyperbole over the Who’s “I Can See For Miles” (McCartney took it as a challenge to write something that actually matched the critic’s description), this song has some well-known historical issues with people reading unpleasant (to say the least) meanings into it, but to be fair, if you write a song about a fairground slide that sounds like Satan having an orgasm, people are inevitably going to get a little confused. In any case, no rock song in history had come anywhere near this close to Heavy Metal before, and it remains a crucial milestone of the genre’s development and an absolutely amazing song in its own right. If by some bizarre chance you haven’t heard it, go listen to it. Right now.
