On September 19, 1981, Paul Simon and Art Garfunkel played in front of 500,000 people in Central Park, New York City. I missed this concert by three days, as I had to end my first ever visit to the US to go back home to prepare for starting at Edinburgh University, but I saw them play much the same set live at Wembley Stadium the following June - a highly memorable experience even 30 years on.

Contrast this with a 2014 drone's view of London.
