Reznor performed a new version of "Piggy" on piano with a string quartet at Neil Young's 2006 [[Bridge School Benefit]] concert. This was most likely the inspiration for the "Ghosts Piggy" arrangement that was used in 2008's [[Lights In The Sky Tour]]. It features [[Justin Meldal-Johnsen]] on upright bass and Reznor on shaker and marimba, usually segueing directly from "[[19 Ghosts III]]" via Reznor's shaker playing as it slows from the quicker tempo to match that of "Ghosts Piggy". Its title is sourced from tour setlists.
The "Nothing Can Stop Me Now" remix version has been performed on the [[Dissonance]], [[Wave Goodbye Tour|Wave Goodbye]], and [[Peel It Back Tour|Peel It Back]] tours.
