1. Low-Life was preceded by the release of the single for "The Perfect Kiss."
The original version of "The Perfect Kiss" was almost nine minutes long, but when the song turned up on the subsequent album, it was in a shortened version which lasted a mere four minutes and 50 seconds and, in addition to other edits, dropped the third verse, which - d'oh! - is the verse where the words of the title are actually sung. In fact, the complete, unedited version of "The Perfect Kiss" didn't make it to CD until New Order's catalog was reissued and expanded in 2008.
That's right: if you go back and check out the original CD release of Substance, you'll note that the song is missing almost a minute of its original run time. While the shortening was originally done because of the space limitations of CDs, technological advances have allowed for longer-running CDs since then, yet the shortened version still remains. Go figure.
