The night of the [Butthole Surfers] appearance at the huge Pandora’s Box festival in the Netherlands, [bassist Mark] Kramer went to fetch [singer Gibby] Haynes for a sound check. “It is firstly most important to state that, on this night, Gibby had eaten an entire handful of four-way acid tabs and drank an entire bottle of Jim Beam before the sound check had even begun,” Kramer notes.
