I took a look around and ended up in 1915, with P. G. Wodehouse commenting on cabarets:
The financier fox-trots round the floor, his brow creased with thought. He is bumped into by another financier, who has not yet completed his course of lessons at the correspondence school of modern dancing. It gives him the idea he has been seeking since dinner. When the music stops, he goes over to the other man’s table.Seems like only yesterday. To be sure, they don't fox trot anymore, and the Pennsylvania Railroad has long been absorbed into CSX (via Conrail, via Penn Central), but those rich 0.01%ers are still buying and selling the rest of the world as though we were pieces on a Monopoly board.
“Hello, Jimmy!”
“Hello, Clarence.”
“Say, listen, Jimmy, old man, just a minute. I’ve got an idea.”
And then they sell each other the Pennsylvania Railroad.
Who knows what other riches lurk within those pages? Ah, here's a set of 1940s jazz photos by Herman Leonard, Nick Tosches on the Ed Sullivan Show, from '34 John Gunther asks "Has Hitler a Mother Complex?" (ah, Freud), back to Alexander Woollcott on Harpo Marx, and then there's Princess Di.
Happy grazing.
