"Immermannstraße" is named for a street in Düsseldorf's Japanese town which Dinger was introduced to by Kazu and Miki soon after meeting them.
"Cha Cha 2008" is a cover version of La Düsseldorf's song "Cha Cha 2000", which emerged spontaneously from a jamming session between Kazu and Klaus in 2008, later being overdubbed with vocals and synthesizer.
