The Concert in Central Park was a free benefit concert on 19 Sep 1981 in Central Park, New York City, where Simon & Garfunkel performed in front of more than 500,000 people. You can watch the 1h 26m documentary on Amazon, Google Play, or other providers, but the videos below seem to be of much better quality than the documentary. The audio seems to have been digitally remastered and the stereo separation is enhanced.
These videos are provided by Simon & Garfunkel through the VEVO partnership on YouTube, made publicly available in 2015. The song performance tracks are provided here in alphabetical order. Some of these videos include YouTube ads that you can close or skip. Not all the songs from the event are below. At the bottom of this page is a nice news report about the event, also provided by Simon & Garfunkel.
