Peter gave the outlines. V. Havel and other dissidents in Czechoslovakia (from ex-Czech CP officials and intelligentsia, progressive Christians, Trots at the time [blanking on his name, now he is Czech rep. to OSCE, another Prague Spring neo-marxist, Karel Kovanda now liases with NATO]) founded Charter 77, in 1977, to agitate for the release of the avant "progressive rock"/jazzish group, Plastic People of the Universe. They had been thrown in prison. They played (still around, I saw them on tour) Zappa and Velvet Underground songs and original tunes. Michael Pugliese
