Nagging PSB "musical mysteries"

Here are what I consider to be the most pesistent, nagging mysteries related to the music of the Pet Shop Boys. Please note that I'm including only mysteries directly regarding their music. I know a lot of my fellow fans have questions about their personal lives, but that's simply not my interest here.

  1. In "Electricity," from what movie(s) or TV show(s) were those samples of dialogue taken? "What does this mean?" (long mistakenly heard as "What does it mean?"), "What are you doing in San Francisco?" and "Get out of here and take this cake with you!" As far as I'm concerned, this is the biggest PSB musical mystery, bar none. The really scary thing is that Neil and Chris themselves may not know, in which case it may remain a mystery until a PSB fan (that is, someone familiar with the song, which probably indeed limits it to fans) just happens to hear those lines while randomly watching whatever old movie or TV show it is.

    SOLVED! - Finally, on January 27, 2019, of my site visitors alerted me to his discovery of the movie from which those samples are taken: the 1942 film My Gal Sal starring Rita Hayworth, who's the woman delivering those lines. All three lines occur in quick succession starting at about 1:40:52 into the movie (as it appears on YouTube). Thanks to Kurt Belliveau for solving this mystery!

  2. In "To Step Aside," from what recording(s) were those samples of gypsy vocals taken? And what are their English translations?

  3. Do the following Pet Shop Boys tracks actually contain samples of these recordings by other artists, as has been speculated, or are these speculations mistakes or misunderstandings?
