I found a bit dressed down version of UP, where you can hear more clearly these more unorthodox sounds.
So, is the sax that sound coming in 1.06? Also 1.57 and maybe most clearly 2.40? Sounds a bit cacophonic to say the least, perhaps good thing that they buried it in the mix!
Also, couple of strange sounds..
One coming on in the intro, 0.17, most likely a synth, but sounds almost like a vocoder to me?
Also that sound that plays two tones, starting in 2.48 continuing to the end. What is that? Sounds like some strangely distorted guitar or electric piano?
Correct me if (and when) I'm wrong but to me it sounds like two different persons playing piano on the verses and the rest of the song (not counting that two toned motif).
On the verses the piano playing sounds a bit sloppy to me (Bowie?) and on the rest of the song it sounds more delicate and professional (Richards?). I might be just imagining.
Also, who played the organ on the bridge? Mysteries, mysteries.. :-)
