What is that "coon" all the comics sing about?

Mister Brown—John James!

If as to me Mister Bull has a doubt,

Go on!—I'll say.—My names?

Chorus.

Why, they're Ab-dur-rahman, son of Afzul, son of Dost

Mahommed, wearer of the Afghan Crown.

Don't you know me?—Go on?—Well, you will very soon,

For I'm Ab-dur-rahman Khan, the dandy Afghan coon!
