Accordionist and composer Siggi Haider not only knew Werner Pirchner personally and recorded the 'Sonata vom rauhen Leben' with him in the recording studio, he also plays on the accordion that Pirchner, who died in 2001, had specially made for him. Together with daughter Juliana (saxophone and vocals), Siggi Haider interpreted works by Pirchner, such as excerpts from the "Kleine Messe um C", and by Bert Breit at a concert in October 2023. The audience was then allowed to choose a work from LaChapelle's Bible cycle, to which father and daughter performed a clever and much applauded improvisation.
