Watch this, young and old alike - from last November. Beyond "well past his prime" and should have hung up the guitar years ago is the first thought. Very sad is the next emotion. Not even playing the guitar. Very difficulty breathing at minute 1:00 +. Age 86, some claim he had pneumonia while performing this. Then, if you look deep into their eyes, you see proud, classy people "pressing on regardless". I hope I have the resilience in old age to carry on proudly. Kudos to the old legends - good, bad, and whatever. Kudos to the young Kacey Musgraves for her respectful duet.
