Is it possible, that despite my normally impeccable standards I was in unseemly haste and unseemly taste to embrace Die Antwoord quite so urgently?

It may be so.

I was overcome by sentimentality/pride at hearing English spoken with a heavy South African accent without embarrassment. Plus provinciality, the excitement of seeing someone from your small town make good in the capital.

Wikipedia tells me that Ninja of Die Antwoord is maybe 46 years old, and an accomplished guy before this. Die Antwoord is funny, and is closest to Ali G doing Eminem.
