I saw them in concert three times over the long decades. The last time was 15 years or so ago and we all thought they were done touring. They just keep making music. I see a lot of "the were" in the thread. I know they have slowed down, even the Stones have slowed down the music making. The Wuhan virus slowed all tours down, but they have shows planned from June to October this year.
