The song is performed in a lower key, presumably due to the vocal strain required to sing it as it appears in the album.
The song debuted at[[2007/02/11 Lisbon, Portugal|Lisbon, Portugal]], and was played (at least) at [[2007/02/26 Manchester, UK]]; [[2007/04/04 Frankfurt, Germany]] and [[2007/04/18 Los Angeles, CA]]. Bootlegs for many of these three other shows exist, not least the last, released by NIN themselves.
The piano solo outro is greatly expanded in the live versions.
