Jackboot is a clip from Pastichio Medley (~12:43-12:57). This instrumental often followed Silverfuck during Siamese Dream era concerts.
\"This is our growingly infamous riff collection of practically, but not almost, every idea that was attempted for Mellon Collie that didn't even make B-side status. I sorted through hundreds of hours of rehearsal and album tapes, and kind of randomly ran small bits all together to create a pastiche of madness. The original titles were all used.\" - Billy Corgan, Guitar World, January 1997
