Looking to ID Robert Cray song on recent years' Crossroads...

[poodlesrule]

At Crossroads, two or three years ago, Robert Cray did a very long song, which I caught by chance on local PBS station. I was paying so much attention to his focus on his artistic rendering the song that I forgot about the song itself!

Could someone familiar with the Crossroads of two-three years ago please identify the song for me?

Found it: "Poor Johnny" , more like four years ago though.
