The set includes a 108-page book containing a historical essay, interviews, original scripts, and collages by Firesign founder Phil Proctor.
The collections were digitally remastered and annotated by the group's archivist and producer, Taylor Jessen along with several contributors including Mike McIntyre [2] Dear Friends and Let's Eat are each collected in both their original broadcast versions and later syndication edits.
[7] Proctor told the Library of Congress in an interview that the material was gathered from archives in "our basements, garages, sheds" and "entire reel-to-reel recordings" made by fans during the original broadcasts.
[9] The album was released on Seeland Records, the label run by experimental band Negativland; co-founder Peter Conheim cited Firesign Theatre as a direct influence on Negativland and hailed them as "pioneers of freely improvised radio".
[10] The group's 1972 compilation album Dear Friends was collected from the same radio sessions gathered in Duke of Madness Motors.
