Dunno if anyone's ever noticed - but on "Closer To The Sun", about 6m40s in, very faintly in the right channel if you're listening on headphones you can hear the tune "Swedish Rhapsody" in the background. Anyone got any idea whether there's any significance to this? I wondered whether it might be an obscure reference to short-wave 'numbers stations' (one infamous instance of which uses that tune as its signature).
