Ah, Geography (Part 2)

The same boy as the last post.  We were now looking at The Entertainer.

Me: Who wrote this piece?
Boy: Um... [I point and, internally, roll my eyes] Oh.  Scott... Joh..pline...
Me: Scott Jop-lin.  Where do you think this guy is from?
Boy: France?
Me: Er, no.
Boy: Ooh, England!
Me: No - but somewhere they speak English.
Boy: Um... Italy!
Me: Ah... no.  Could he be Australian? 
Boy [shaking his head]: I don't think so.
Me: But don't we speak English here?
Boy: Yeah, but I don't think he's from here. [under his breath] Scot...
Me: No, he's not from Scotland.
Boy: I know that.  Oh!  Where else speaks English?  That's not England?
Me [knowing this could take forever]: Do they speak English in America?  Could he be American? [I start nodding really obviously]
Boy [looking rather unconvinced]: Yes?
Me: Yes.  Scott Joplin was American.
