Re Lloyd's schoolkids:
"anyone have the exact quote?"
I've actually heard it quoted as 'Paki', which I have always taken to mean "exotic"

I thought it might have been 'chinky' (apologies all for racist language), meaning 'exotic' certainly, but also perhaps signifying the unfamiliarity of modal scales.

I'm glad I'm not the only aficionado of Mongolian throat singing, Jim - I'm afraid my treasured recording of Altai-Hangai is a bit of a room-clearer around these parts.
