This is one of tracks that really stood out for me on the first couple of listens. One thing, is it me or is one of the pad sounds actually someone speaking? It's the one that starts about 22 seconds in, I can't really discern what it says but the first note really sounds like a time stretched "I" to me. I've convinced myself it says "I don't mind" or maybe "I bye bye" even though that makes no sense.
Also, the kids chopped up voice and the few adult sounding stabs really remind me of one of the live tracks that's out there, it's quite uptempo but I don't really know how to write down the choppy vocal, it kinda like "A ch, a boo, a ka" to start and then it's more vocalised when it kicks but it's still gibberish' like "Ah der der do, Ah Pikachu, ah doopy doo" or something and I seem to remember there's some kid that says "beautiful" at the beginning? I've made a right dogs dinner of that description but anyway yeah, it sounds like it might be the same voices to me.
Edit: this is the track I was thinking of http://www.youtube.com/watch?v=2Mfj4dnfAhs and now I've heard it again the voices are totally different to how I remembered them so ignore me.
