Afrikaans nursery rhyme in Elysium

This is a famous nursery rhyme that most Afrikaans people will know! Jan Pierewiet is a kind of bird found in South Africa with a very distinct call.

It was sung in Matt Damon’s movie “Elysium” by Sharlto Copley, a South African actor that also played in “District 9” and “A-team”.

There are many videos of this song on youtube, note that none-native speakers often pronounce "stil" the same way as "still" in English, which is not entirely accurate.
Can you hear the difference and pronounce it correctly?
