If you wanted to, you could set up these tunes to have improvised elements.
We can to a certain extent, but it's difficult. Most of the improvisation is done between the gigs. We change a lot of the tracks in rehearsals. I told the guys "I'm so ****ing bored of 'Karmacoma' that I wanna change it." So we put new parts in it—a new intro, new middle section and a few new lyrics. And it's still ****ing boring! But it sort of spices up the boredom a little bit. [laughs]
