There’s also some story somewhere about him hearing another folk singers arrangement of Scarborough Fair - this other guy didn’t know anything about copyright © but Simon knew that you could copyright © new arrangements of traditional songs. So he invited this guy round for dinner and asked him to show him exactly how he played this arrangement and then the next day went and copywrighted it.
Not really as big a deal as the aparthaid stuff but evidence of obvious twatdom.
