I've posted separately, but I'll put it here too:

Henry Lawson's "Do You Think That I Do Not Know" is in the DT here, and refers to the tune by Slim Dusty (as recorded by Martin Wyndham-Read, also by Priscilla Herdman). I can't get the midi to work, though.

This site has the tune by Chris Kempster.
