“Argentina was a very volatile country that was ruled by Los Generales, as they were called. […] The authorities had given their approval for our concerts, but they were nervous about the danger that could be posed by so many people gathered in one place, so that throughout our stay a heavily armed security guard accompanied us. Everywhere there were armored cars with squads of about forty motorized policemen loaded with automatic weapons.
The background was tough, but at the same time we had a great time. On the way to the concert, they would stop traffic on the highway and clear it so we could pass. We used to shout and howl with the entire police escort while they did little races and stunts.” — Brian May.
