It'll Aggravate Your Soul is a song, according to the Carter's Biography, that was written entirely by A.P. Carter even tho the first verse appears to be based on other lyrics.

It's one of the few songs AP sang solo and it was written during the time when he and Sara were seperated.

IT'LL AGGRAVATE YOUR SOUL Carter family- 1934

          Come all of you people take warning from me
          Don't take no girl to Tennessee
          For if you get married and don't agree
          It'll aggravate your soul

          We left Maces early in the night
          Expect to get married before daylight
          So many things happened to hinder our flight
          It aggravated my soul

          Arrived at The Bristol at 11 o'clock
          The parson was there right on the spot
          We found that the license had been forgot
          It aggravated my soul

          We went for the license in an automobile
          Run so fast couldn't see the wheel
          No on can explain how bad I did feel
          It aggravated my soul

          We stayed all night at The Bristol Hotel
          Just to make folks think we were swell
          Next morning they put it in the Bristol Herald
          It aggravated my soul

          And when the new style books comin' around
          She begins to get ready to go to town
          You know right then she's milliner shop bound
          It'll aggravate your soul

          She wants a new coat and a hobble skirt
          And you can't get in for the young un's and dirt
          And when she gets out, oh how she will flirt
          It'll aggravate your soul

          And when depressions gather round your head
          You'll think of what your dear old mother said   
          With a pain in you back and heart and head
          It'll aggravate your soul

          Now young men take warning from me
          Don't take no girl to Tennessee
          For if you get married and don't agree
          It'll aggravate your soul
