It should also be noted that John Williams gave us perhaps the clearest giveaway. He used the Emperor's Theme during all of Sidious' scenes in Menace and Clones. Emperor = Palpatine, Emperor's Theme = Sidious, therefore, Palpatine = Sidious. And also the fact that the celebration music at the end of Menace is the Emperor's Theme in happy-mode.
Holy shit! I still hate that piece, but now it gets an additional meta layer at least... thanks! :D
