"They have the time, the time of their life," Frank Sinatra sings in "Chicago." "I saw a man, he danced with his wife, in Chicago, my hometown."
Now, Chicago is my hometown too, so I am not as familiar with many other American metropolises as I am with that toddlin' town. I can say that in Chicago, when you see a man dance with his wife, it is generally not worthy of note. Are there places where this is not the case, such that coming to Chicago and seeing a husband and wife cutting a rug, one might see fit to include that detail in a song?
