This work was first published in South Africa and is now in the public domain because its copyright protection has expired by virtue of the Copyright Act No. 98 of 1978, amended 2002.

It is a broadcast or sound recording and 50 years have passed since the year the programme was published. It is a cinematographic or photographic work and 50 years have passed since the date of its creation.
