That was great, Dave. For me, goose bumps don't lie, and I had them watching that one.
I caught a performance when Sammy was touring with Frank Sinatra and Liza Minnelli in Houston years ago. I thought Sammy stole the show from those other two great performers, not an easy thing to do, and "yes," Sammy did "Mr. Bojangles." I am of an age where I watched him from his first national exposure as a young man on the Ed Sullivan Show until his end. Quite a career.
I have always thought it unusual that that song was written by a country artist, Jerry Jeff Walker, who I heard perform it too in a small venue. His was not the equal of Sammy Davis' though, even if he did create it. Many, many have sung the wonderful song, but few the equal of Davis in my mind.
