One of the sweetest voices of soul’s golden era in the 1970s, Bill Withers is best known for hits like “Ain’t No Sunshine” and “Lean on Me,” about growing up in a West Virginia coal mining town. In 2010, Withers joined us in studio to talk about the documentary Still Bill, which chronicled his life and career. Bill Withers, the artist behind the classic “Just the Two of Us,” and “Grandma's Hands,” (it was his favorite song), died on Friday at 81.
