ok let's make it simple
US: has 2nd switch remix (reggae mix w/ Elephant Man) as hidden track
UK: has Comin' 2 The Stage and We Won't as bonus tracks + Elephant Man hidden track
other variations: some countries have only Comin' 2 The Stage as a bonus track + the hidden track
so, EVERY CD has the hidden track with Elephant man, it's just a matter of who gets the bonus tracks. UK gets 2 bonus tracks, Australia got 1 bonus track, and i think there might be some other countries that got bonus tracks too
