Hmm @BanjoBen I may have missed it the first time watching, But I sure heard it today Sir! Some folks (not just me ) like to use all their senses. TAB is my sick’s sense. If I can’t see it, I am sick. 
Seriously though, my reason for revisiting this lesson today is to help me with the Inside Cabin Camp: Chord Scale Transitions with KSB Lesson as I struggle to memorise the physical locations of the Minor and Flatted 7th chords.
On this occasion KSB’s TAB Handout didn’t help much. So it’s always good to have an alternative data point or reference point to help resolve a query. Since I don’t use Minor and Flatted 7th chords often, “at my age I forget things easily.” That said I may have to go revisit Minor Mingle to get in some practice.
