Simon And Garfunkel - america live, 1981

"The concert took place on Saturday, September 19, 1981, on the Great Lawn, the central open space of Central Park. The first spectators, many carrying chairs or picnic blankets, arrived at daybreak to secure a good spot. The Parks Department originally expected about 300,000 attendees. Although rain fell throughout the day and continued until the start of the concert, an estimated 500,000 audience members made this the seventh-largest concert attendance in United States history."
