I didn't know my baby loved me so   Until that letter come to let me know   Now I pack my bags and then I'll go   And catch the first train I see headin' south      If I'd got this letter in Idaho   Where snow's so deep it wouldn't let me go   I'd went hog wild and melted all that snow   And caught the first train I saw headin' south      If I got this letter in Iowa   Nothin' in this world could make me stay   I'd grab my hat and then been on my way   And caught the first train I saw headin' south      I didn't know my baby loved me so   Until that letter come to let me know   Now I pack my bags and then I'll go   And catch the first train I see headin' south      I didn't know my baby loved me so   Until that letter come to let me know   Now I pack my bags and then I'll go   And catch the first train I see headin' south      If I?d got this letter in Ohio   With a busted back, two arms and a broken toe   There'd be no hesitation, I would go   And catch the first train I saw headin' south      But I got this letter up in Maine   You can bet your bottom dollar, I feel the same   Every clickety-clack of the driver's call her name   As I ride this first train I caught headin' south      I didn't know my baby loved me so   Until that letter come to let me know   Now I pack my bags and then I'll go   And catch the first train I see headin' south
