Call it "middle-aged dude trying to still be Superman" or whatever....stuff happens.  I sustained a very minor yet painful injury to my chording hand which caused me to build-in some workarounds to my playing.  As of this recording, I'm actually doing much better but for several weeks, I felt like I needed to make some adjustments to my guitar playing so that's what I chat about as I drive to a July 4th gig in the Great Smoky Mountains.
