Last line of Dark Side of the Moon, by the same guy who’s been yammering and chuckling throughout. Mr. Rilch and Friend say that he was some misfit street person they called into the studio on a whim. I was told, by another friend who’s a big PF fan, that he was one of their roadies. Anyone?
A lot (thought of course not all) of the spoken parts were done by Roger the Hat (“Live for today, gone tomorrow, that’s me, hahaha…”, “…short, sharp, shock…”), who was a roadie for various bands (not for Floyd, I don’t think). The spoken parts come mainly (if not entirely) from answers to a set of questions Waters asked of several people, such as, “When was the last time you were violent?”, “When was the last time you thumped someone?”
I always thought it was R the H who did the final bit you mention (and I’ve found some sites claiming that), but according to this site (which I just ran across), that part was done by an Irish doorman for Abbey Roads studio, Jerry Driscoll:
I have also that Paul and Linda McArtny taped answers to the questions but they were so used to being interviewed that their responses weren’t ‘real’ enough to be used.
