I believe the answer is:
otis
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">soul singer redding</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for otis that I've seen before include "---- Redding, 1941-67, soul singer" , "Cole Porter's miss who was "unable to lunch today"" , "-- Redding, US singer" , "US inventor" , "regretful lady" .)
