Five years ago when we moved to Indiana to our new apartment we didn't have cable so my husband went out and bought a few movie, one of which was "O, Brother Where Art Thou?" which we promptly fell in love with. We loved the story and the music, our favorite song was "Constant Sorrow". A couple of years later I was channel surfing and happened upon a tv concert of the of Allison Kruass and Union Station and for some reason I watched that show and was pleasantly surprised when they sang "Constant Sorrow".
