Porter, a fan in Milwaukee, and Lynn Hudecek, a fan in Cedar Rapids, Iowa. Porter wrote an
appreciation of the band (1971). The monograph "Viking Accordion Band reflects colorful
history," (1992) by band leader Leighton A. Berg features anecdotes, photographs,
advertisements, and ephemera detailing the bands history. The sound recordings are original
78-rpm audio discs on various labels and comprise the entire recorded work of the band. Two
compact discs, digital transfers of most of 78s in the collection, were produced by Mills
Music Library in 2021.
