"And, ag man, sommer anything in Afrikaans, man"

ANC activists in exile or in military training abroad would become homesick and eager to read books and newspapers from South Africa, even those in Afrikaans, the oppressor's language.

Sommer is a much used word when speaking both Afrikaans and English. It has no meaning as such and can be translated as "just" or "even". "Sommer now" might be "right away" or "straight away".
