Well I didn't see any reason to keep TheSession's illogical key signature, I figured maybe it was some software glitch that produced that, so I went ahead and wrote it the way I thought it should be written. (By the way, her, not his.)
So my next contribution to the musical cause here, is my revised guesses as to The Long Lane CHORDS, with arthritis-friendly fingering diagrams for mandolin, guitar, and ukulele (view in browser, or click Download button to print PDF). Slightly different batch of chords than in my first video in this thread, because some of my earlier chords were starting to get on my nerves a little. They still might not be entirely right (my ear isn't good enough to know for sure), but anyway here's the MuseScore MIDI simulation of the new chords:
