Istanbul, not Constantinople

We were out walking Dilly early on this hot and humid day.  We passed a car parked across the street. It had an odd sticker in the rear window. It said, "Make Istanbul Constantinople Again."

Right away a fragment from an old song from the 40's began playing in my head. I asked my husband about it. He remembered it, too.  Here's all I remember from that song:

It's Istanbul, not Constantinople,
Istanbul, not Constantinople,
It's Istanbul, not Constantinople,
Why did "Constantinople" get the works?
That's nobody's business but the Turks.

A little later, more lines surfaced from the old memory fishing bank:

Even Old New York
Was once New Amsterdam.
Why they changed it
I can't say,
Maybe they just liked it better that way.
