The Kinks' "Party Line" (1966) is actually the least dated song here because the party line is actually a metaphor for private vs. public identity (even with a bit of gender indeterminacy and political skepticism). We're in the same situation today even though our cell phones offer us the illusion of privacy: https://youtu.be/O8rApRZFIsg

Ditto for their Dylanesque "Long Distance" from a decade and a half later: https://youtu.be/YkHMcDiuQ8U
