The demo version (as you call it) is exactly the same version featured in bounce... well, half of it, cause it is only the right (or left, I dont remember right now) channel of the "actual" version of everyday (is becouse of this that we can hear Richies line clearly, cause Jon's part is in the missin channel).
And the "whisper" is nothing but a jingle from the radio station (kiss FM) sayin' just that, kiss FM, to avoid people recording the song.
