Found this (that I’ve never before seen or heard) thanks to the every-loving Boing Boing: Ray Charles covering the hell out of “Ring of Fire” on the Johnny Cash Show:

UPDATE (8.7): I meant also to add there’s a personal significance to seeing these two legends together in this clip, as they represent half of the first music I adored as a child. I couldn’t tell you how many times Cash’s “Boy Named Sue” and Charles’ “Hit The Road Jack” I played over and over and over and over. And over. The other two were Henry Mancini’s “Baby Elephant Walk” from the sountrack of the movie “Hatari,” and Rossini’s “William Tell Overture,” better known to me then as the theme from “The Lone Ranger.” The moment any of these songs would finish I’d race back to my mom’s Admiral hi-fi and move the needle carefully back to the beginning and start it all over again.
