I very much was thinking his last live show before Christmas was almost a “goodbye”. Perhaps over the holidays Rush recorded a special show to be played for us in case he can’t return again. I hope that is not anytime soon, of course.
I was thinking the same thing when I listened to his last live show. Like you, I was also thinking that, knowing he will be unable to resume his show, he might record some type of "farewell" to be played at the appropriate time. If so, I hope we do not hear it anytime soon. Prayers for Rush.
I felt that Rush’s last show sounded like he was saying goodbye to all of us as well. It brought tears to my eyes.
