My wife and I just saw his stage production/rock opera "Ian Anderson presents the story of Jethro Tull as told through the music of Jethro Tull"
Even at his age he was running all over the stage and can still play the hell out of that flute.
I caught a Jethro Tull concert in the ‘90s. I was never any huge fan of their songs but it was a great concert. They are the kind of band you’ll always be glad to have experienced live.
