Hello slimjim... 18 days, 10 hours and counting 'til we find out! There are any number of bootlegs out there featuring most of the tracks that were slate for Smile (in, for example, the running order on the unfinished but published cover art). And of course several of the tracks were released officially on other albums -- Good Vibrations, Vegetables, Surf's Up, Cabinessence etc etc. But you're right - we don't know if any of them ever reached the stage that Brian wanted them to reach. Though I suspect many of them did. Importantly (for me), judging by the Pet Sounds tour he will be faithful to the sound he had in his head in '67 rather than any concept of what a 2004 record should sound like, and for that we must give thanks. We shall doubtless have much to say after the concerts!
