==Live==
This song has been played very faithfully to the album version since 1994. However, it can be considered a setlist rarity because it has only been played on the [[Self Destruct Warm-up]] tour (twice), [[Performance 2007]] tour, [[Wave Goodbye Tour]] and , the [[NIN 2022]] tour, and the [[Peel It Back Tour]].
