Snippets of voices between and over the music are another notable feature of the album. During recording sessions, Waters recruited both the staff and the temporary occupants of the studio to answer a series of questions printed on flashcards. The interviewees were placed in front of a microphone in a darkened Studio 3, and shown such questions as "What's your favourite colour?" and "What's your favourite food?", before moving on to themes more central to the album (such as madness, violence, and death). Questions such as "When was the last time you were violent?", followed immediately by "Were you in the right?", were answered in the order they were presented. Roger "The Hat" Manifold proved difficult to find, and was the only contributor recorded in a conventional sit-down interview, as by then the flashcards had been mislaid. Waters asked him about a violent encounter he had had with another motorist, and Manifold replied "... give 'em a quick, short, sharp shock ..." When asked about death he responded "live for today, gone tomorrow, that's me ..." Another roadie, Chris Adamson, who was on tour with Pink Floyd, recorded the snippet which opens the album: "I've been mad for fucking years absolutely years". The band's road manager Peter Watts (father of actress Naomi Watts) contributed the repeated laughter during "Brain Damage" and "Speak to Me". His second wife, Patricia "Puddie" Watts (now Patricia Gleason), was responsible for the line about the "geezer" who was "cruisin' for a bruisin used in the segue between "Money" and "Us and Them", and the words "I never said I was frightened of dying" heard halfway through "The Great Gig in the Sky".
