I think the more interesting version is the live one on 5YIAL. But again, tastes.
While the acoustic rendition of the song certainly works, I think the best versions were the ones on the Six Degrees tour. They kinda beefed it up with the small 'CME jam' towards the end, and there's a few extra doodley bits from JP and MP goes a bit crazy aswell. The extra bulk kinda makes it feel more like a standard DT song (whatever that means) as opposed to the version of the demo which qualifies as one of DTs shortest songs.
I swear I had a CD with this version somewhere but I just had a look and have no clue what I remember hearing it from. But I found a vid on youtube that sounds like it might be similar to the the one I remember:

https://www.youtube.com/watch?v=pBP4L0kK_q8 Got a much 'busier' solo from JP on this one, exactly what the song was missing IMO.
Still don't think it's the one I remember though, it seems like there's subtle differences on each version and this one the guitar solo is a reference to something familiar that I can't pinpoint, some kind of classical tune? Can't put my finger on it.
