I recently rented the Tom Hanks movie, "The Ladykillers." The Coen brothers are known for including older spirituals and blues music in their movies, but I was very pleasantly surprised when the credits started to roll at the end of the film, and I heard Blind Willie Johnson's raw, distinctive voice coming from the TV, sincing "Let Your Light Shine on Me." That was good enough for me, but then there were actually additions to Johnson's original track, as they added percussion, and a chorus of backup singers. It was great!
I tried to tell my wife how cool it was to see a mainstream movie featuring such an underappreciated blues singer. She kind of gave me the "okay, he's talking about that goofy blues stuff he likes again" look.
