The core of this track is identical to 1980, but the beginning is brand new. Instead of having a definite start (as with the high-pitched staccato chords), this version almost creeps up by surprise. The chord sequence enters first, from a new bridge from the previous piece, followed by a faded-in bass sequence. The first section is shorter than its 1980 counterpart. The second section, however, differs more fundamentally from its elder sibling; whereas the 1980 version had no modulation whatsoever, and relied upon some attractive interweaving lead lines to keep the interest going, this rendition has a revolving chord sequence throughout (i-iv-v-iv-v-i).
This is a piece that can be thought of as being divisible into three sections. The first part takes its rhythm section from Dr. Destructo (same percussion and bass sequence), but with chords played over the top rather than a guitar-sounding patch. The second is a mostly percussive bridge, rather train-esque in nature, which becomes the third part, a repeating six-bar phrase continuing with the train-sounding percussion.
This bridge piece, with heavenly voices mixed in with "sparkly" effects and some industrial-type noises distinguishing it from the version played in 1980. This bridge piece is the only difference between the second sets of autumn 1980 and winter/spring 1981.
While traditionally encores are single songs, this one was played as part of a "medley", leading smoothly and without a break -- or bridge -- into a short version of Scrap Yard.
(All times rounded to nearest 15 seconds and include bridges following song, if any.)

Notes
The spring 1981 tour took in venues not included in the autumn 1980 tour, and gave them essentially the same playlist. The second set was virtually identical; the first set was edited early on to fit in the mini-epic Thermal Inversion.
