Dicho,I listened to that part a few times trying to hear "to my 49". I'm pretty sure it's seems like. However, that's not to say that we're both listening to the same version. The one I have is from his "Man Of Constant Sorrow" CD which was released after O Brother. This version was originally released on his Lonesome and Blue CD. But it appears that Ralph has been doing this one for a long time, perhaps an earlier version said "to my 49".
