I would just as soon have Jack Johnson the singer ahead of Ray Leonard and Pernell Whitaker. The difference in sense that either make there is negligible to me. Although the original first thirteen names looked pretty good to me, overall. They're very close in line with mine, for who's is there, which is why the Johnson part gave me a deep, burning pain in my sack. Of course, I was technically sitting on lefty, at the time, but that's probably a coincidence. Good day to you.
I only know his name from getting the wrong Jack Johnson on youtube. If you became popular as a musical act after about 1990, there's a very good chance I won't know you, no matter how popular you are. I still refer to Robert Cray as "one of the newer guys". I did see Johnson parodied on a sketch comedy once, so I have an idea what I'm missing. I can manage okay without it.
