Glenn, I find it amazing that you were able to keep up the schedule last year and perform 2 hour shows when you were in so much pain with the knees.

Sending you much love and best wishes for a speedy recovery!

I know, from my own experience, it costs a lot of energy.

Two years ago my I had to undergo a knee replacement, it was the result of a car accident 30 YEARS earlier.
The last couple of months I could only walk with crutches. But still I went for a walk with my dogs every day for at least 1 hour a day. The dogs, one died last year, were everything for me.
Beside the replacement they had to correct my leg, it was crooked.
With a lot of dedication and the desire to be able to walk (ride a bike) again, I was up on my feet in a couple of weeks.

Amazing Glenn! Thanks for the chance to interact with you!
