Hi Ben,
I heard you have a direct connection to Santa who is more busy than usual these days. Not only packing gifts, feeding elks, polishing his sleigh (Craig Ferguson would ask at this point if "polishing his sleigh" is a euphemism), but also carving sounds with probably trembling hands in the arctic cold.
So... could you please drop him a note and ask if he would tackle the lead sound from David Bowie "Ashes to Ashes". It comes in maybe 30 seconds before the fade out. I think Nick Plytas freestyled this one and to this day it's one of the most beautiful and haunting sounds.
The other one would be equally cool: any of Richard Barbieri's sounds from Japan's "Ghosts". Not sure if they were done on a Prophet 5 or a System 700.
merci
