Redding who sang, "Sittin' here resting my bones / And this loneliness won't leave me alone" (4)

otis
(Other definitions for otis that I've seen before include "Cole Porter's miss who was "unable to lunch today"" , "Company providing lifts" , "US inventor" , "- - Redding (soul music star)" , "lift company" .)
