Bill Withers - Ain't No Sunshine

Happy 73rd to Bill Withers, writer of such classics as "Lean On Me", "Lovely Day" and "Ain't No Sunshine". The latter is by far his most loved recording, a song that's been covered by God knows how many other acts. According to Wikipedia it's at least 144, but there are probably a lot more as well. The song first appeared on his 1971 album Just As I Am.
