Ralph Stanley will sit with David Letterman tonight (11/6) to discuss his autobiography, Man of Constant Sorrow: My Life and Times.

Letterman has dubbed this week as Country Music Week on The Late Show, with musical performances each night from prominent Nashville entertainers. Stanley will close out this theme week talking about his very personal book, written with Eddie Dean. It covers Ralph’s life from early childhood with his brother, Carter, through their time together as The Stanley Brothers, and his own musical career after Carter’s passing in 1966.

We’ll have more to say about this deeply moving autobiography soon.

The Late Show airs on CBS television at 11:35 p.m. (ET/PT).

UPDATE 10:30 a.m. – We just got an update from Norma Morris, of Morris Public Relations, who handles publicity for Ralph Stanley:

“Letterman will mention the book, open it up and make some comments, but Ralph will not have the opportunity to sit down and discuss it. So he will perform one song, Room at the Top of the Stairs. The Letterman people have been just great.”
