What Piggy Muldoon said about migration of NZers to Oz was, in fact, "That should increase the average IQ of BOTH countries."

But most of them came to indulge their familiarity with what they knew best; sheep. Shearing, that is, with wide combs. But I can't recall any songs about the issue, only off-colour jokes that aren't worth repeating.
