He’s absolutely a master musician… but his band Punch Bros has been playing this song for a long time, so he didn’t have to learn it for this performance.
Never heard of these guys until this past weekend, when they performed "Kludd'n" on the PHC rebroadcast from 2013. I was instantly smitten, and I had to have the album it's from, "Mindset". Speaking as a local musical performer in theatre, church and dinner clubs for more than 35 years... Harp Baby, you called it: this is soul-renewing stuff.
