Well, I've now tried Googling with all the following spellings and still failed to come up with any more information.

"Heilan' King o' China"
"Heilan' King of China"
"Heiland King o' China"
"Heiland King of China"
"Hielan' King o' China"
"Hielan' King of China"
"Hieland King o' China"
"Hieland King of China"
"Highlan' King o' China"
"Highlan' King of China"
"Highland King o' China"
"Highland King of China"

I guess we'll have to wait for someone who owns the Miller/Campbell album to transcribe it.
