From the song Istanbul (Not Constantinople):
So take me back to Constantinople
No, you can't go back to Constantinople
Been a long time gone, Constantinople
Why did Constantinople get the works?
That's nobody's business but the Turks
What do they exactly mean by "That's nobody's business but …"?
The former line has already been explained very well, but to be sure to understand all the lyrics, I wood like someone explaining me also the last phrase:
"That's nobody's business but the Turks"
- That only matters the Turks (or whoever), nobody else has the competence to name this city, or:
- This can only be answered by the Turks (that remains the mystery of the Turks), because there is no reason to name it Istanbul.
Which of these two interpretations is right? Or something other?
