Guest K., from the link posted by MMario way up near the top:

      The hit revived Frizells career. Co-writer Marijohn Wilkin then
      recorded an answer disc herself in 1961 with barely changed lyrics as
      My Long Black Veil (The few at the scene were wrong as could be, cos
      the man they had killed that night was with me The scaffold was high,
      I knew his death was near, I stood in the crowd and shed unseen tears
      so there). It has a much less country and more elaborate arrangement,
      a lot of elaborate strings and thudding bass.
