You can think Hello, Goodbye has the profound simplicity of a Zen koan, or it’s just silly and repetitive. Or maybe both ways? I’ve read stories how the word at Apple Corps when Paul McCartney presented this gem was ‘Macca’s really half-assed it this time’ but nobody said anything, because who crosses McCartney. But it doesn’t matter if you find the words meaningful or not. The words could be background noise. The point is all in the unified whole, and that’s catchy as hell. That’s Beatles magic, walking between profound and daft.
