Especially nice up in the shop this morning. How in the world do these jazz cats ever anticipate what, or where for that matter, the root is?! I can only 'hear' it well enough to tell it isn't nearly as random as it sounds.
I just googled "barangrill changes", and up popped all kinds of guitar tabs with the changes written out, and non-root bass notes written under the chord symbols. Other than that, they will have "big ears" from years of practice and experience.
