In an interview (to be transcribed later), Karl Hyde told me that Underworld didn’t use set lists at all until a tour two years ago, preferring to wing it each night, based on the crowd’s vibe. But the sound and light crew requested that they get a list so that they could better coordinate the visual effects that go with the tunes. And the crew actually help make the list each night. This list was from the soundboard. “K.O.S.” BTW, is “King of Snake.”
