In “Under African Skies,” Joe Berlinger's documentary about the making of Paul Simon’s “Graceland” and his return to South Africa 25 years later to perform a concert with the musicians with whom he worked, Simon recounts how back then he wondered whether the songs they were recording shouldn't be more political. He wasn't blind to what was going on in South Africa, after all; he felt the tension. Shouldn't the album reflect that tension?

So he asked the South African artist, General M.D. Shirinda, about the song that became “I Know What I Know.” What were its original South African lyrics? He assumed they would be political. This is what Shirinda responded:

“Remember in the sixties when girls wore short skirts? Wasn’t that great?”
