Yes! Reading that chapter is what inspired me to buy my first 5 Royales compilation, lo these many years ago. It was written by Ed Ward, I believe, who does occassional "rock history" radio segments for Fresh Air. It was in the book "Stranded" in which various writers described their personal 'desert island' record; why they chose it, what's so good about it, yadda yadda yadda. Ward's chapter was completely unlike all the others, and very moving. For a while I reread it obsessively.
Another great single of theirs: "Something Moves Me (Deep In My Heart)" ---the last or penultimate song on the Dr. Horse compilation.
And how about the scorching guitar solo on "The Slummer the Slum"?
