Somewhere aroun 1999 to 2001 -- alas, that's as precise as my memory gets -- I remember reading an interview with Paul in which he mentioned he'd written a number of new songs, and mentioned that several of them were pretty sad. Around that time I remember also reading of a specific track called, I think, "You are Here," which seemed to be specifically about Linda.
I've never seen such a track, even in bootleg form, and only a couple of released songs from that era strike me as sad -- "Magic," being the most obvious example.
So does this mean there's a small pile of unreleased tracks from this period? Does anyone know anything about them? I'm pretty sure I'm not imagining this.
