"Organizations pass, but subversion will never stop being loved."
A great text about prisoners and solidarity, released under the moniker "International Friends" in August 1980 and currently attributed to that Debord guy. Signed by 25,000 people upon it's release, it plead for the release of Basque political prisoners in the spirit of revolutionary solidarity.
"Right away, one shouldn't be able to start a University course, a theatrical performance or a scientific conference without someone directly intervening or letting loose a rain of tracts that pose the questions, What has become of our comrades? and, On what day will they finally be released? No one should be able to walk down any street in Spain without seeing the prisoners' names written on the walls. And the songs that are sung about them must be heard by all."
