Blind Willie Johnson - Dark Was The Night, Cold Was the Ground (remastered 2002)

 The amazing BBC America correspondent Gary O'Donaghue chose this track on his Desert Island Discs this morning with Lauren Laverne and it is well worth a listen (the whole programme too) 

N.B. Gary is blind and his coverage of America is second to none (including a random twenty odd minute phone convo with The POTUS late one night!!)
