On September 19, 1981, Simon and Garfunkel reunited in a fantastic mega concert in New York's Central Park. They went on to tour heavily.
As an '80s kid who also loved '60s music and culture, this concert was of great interest to me. The concert film was often played on our local PBS station, and I taped it on our VHS player. I'd often play back the concert, and enjoy seeing the multi-generation crowd digging the reunion of these two "old friends."
Music was often a multi-generation thing in the '80s, with people of many ages often together enjoying great musical artists. Time was not a boundary.
