I happily stumbled upon this tribute to Mr. Nelson, albeit, somewhat mistitled for this audience :-) I thought it was well done and would make watchers who were not familiar with Bill's work want to take a listen.
It may have been posted previously but I could not find a thread and well, it's worth mentioning nonetheless. Please consider it a "re-issue" if it bears the label "repeated". Of course, repetition is the mother of pedagogy so well worth it. Enjoy, if you haven't seen it.
