The role of Jeff was originally intended for Mothers bassist Jeff Simmons who quit the group just prior to filming. Needing a replacement, Frank Zappa hired Wilfrid Brambell. Within a few days, Brambell walked off the set in a rage and Zappa had to replace him. During a crew meeting, Zappa announced that he would give the part to the next person who walked into the room. Martin Lickert, who was Ringo Starr's chauffeur, was thus cast in the role upon returning from the limousine with a pack of cigarettes for Starr.
