On a 4-mix US promo CD, together with the album / single version, the 12" version and the "Almost Now Edit". This is not a remix, but an edit. The introduction (the slow bit that starts with "When love breaks up") is missing, and the song starts on the first mention of the word "Now!". You can edit this off yourself with a CD player and a pause button.
Almost Now Edit
This retains part of the introduction, up to the line "When the dawn light wakes up" before going into the "Now Edit". A minor but noticeable edit, and not really possible to do at home this time. Only on the same promo CD as the "Now Edit".
Both extremely pointless.
