This is a soulful instrumental. After a full day of recording material for the album, Stevie asked his producer to leave the tape running and to turn down the lights. All alone, he recorded the guitar track on his Fender Strat. Double Trouble added the backing later, including an organ foundation from Reese Wynans.
On the Austin City Limits performance, Stevie introduced this by saying it was "For all the hurting people in the world." (thanks, Paul - Greenwood, SC, for above 2)
