Yes, but I was looking for a contempory example to compare to the contemporary Chavez administration. Post-1970, is there an example of actual outright censorship as in the Alejandro Sanz case? No one in the Bush administration prevented the Dixie Chicks from performing in the US. And the government didn't ban their songs either. Rather, a hysterical and hyper-patriotic public barraged radio (country radio) into not playing their songs. A rather big difference, I'd say.

Seeger is an interesting case. At least he was man enough to back off of support for Stalin, which was and is an indefensible position. I'll have to assume he just didn't have all the data we see today with 20/20 hindsight. Multiple visits to post-Communist Russia and China have proved (to my mind) that totalitarian Communism was indeed as awful as it was portrayed in my childhood. That both China and Russia were hell-bent on destroying our way of life, no I don't see that as being true.

A rambling answer, I know.
