After their reunion concert in Central Park, Simon and Garfunkel went on tour and I got to see them in Vancouver. I still remember Paul Simon talking in between the songs. He said that they had a lot of success during the 60s, and then they didn’t do anything together during the 70s, and here it was the 80s and they were singing together again; and he was really looking forward to the 2000s.
I haven’t been able to confirm it anyplace else, but according to this link[sup]*[/sup], he may have been right.
*The IMDb doesn’t archive it’s news stories, so that link will point to something else within a day.
