I'm feeling like Jayboard. I'm listening to it right now, and this would be about the 5th or 6th time through, and it's just not sinking in. I've nothing negative to say about it, and I do think the tracks form a cohesive whole. I remember Pete Townshend talking about "Tommy" and stressing that the 3-minute pop song had to stand on its own within this "opera" concept. I think Brian was trying with "Smile" exactly what Pete feared wouldn't work. You have to admire Brian for doing it his way, nevertheless.
