"The Marie bit is easy enough to understand, then. The Laura thing takes a bit more explaining, but what it is, I think, is this: sentimental music has this great way of taking you back somewhere at the same time that it takes you forward, so you feel nostalgic and hopeful all at the same time. Marie's the hopeful, forward part of it - maybe not her, necessarily, but somebody like her, somebody who can turn things around for me. (Exactly that: I always think that women are going to save me, lead me through to a better life, that they can change and redeem me.) And Laura's the backward part, the last person I loved, and when I hear those sweet, sticky acoustic guitar chords I reinvent our time together, and, before I know it, we're in the car trying to sing the harmonies on "Sloop John B" and getting it wrong and laughing. We never did that in real life. We never sang in the car, and we certainly never laughed when we got something wrong. This is why I shouldn't be listening to pop music at the moment."
