Best known for his classics “Lean on Me,” “Just the Two of Us,” “Ain’t No Sunshine,” and “Lovely Day,” soul legend Bill Withers is the subject of a new documentary called “Still Bill.”

We talk with Withers about his new film, and about the path his life has taken ? from growing up under the care of his beloved grandmother to music superstardom to quirky conversations he’s had with strangers in Roscoe’s Fried Chicken and Waffles.
