Dust Bowl Refugee = sounds just like Low and Lonely, but, curiously, recorded a couple of years earlier than the Acuff hit (did Fred Rose lift the melody from WG, or are both knocking off an earlier source?).
Jackhammer Blues (or Jackhammer John) and Big City Ways = Browns Ferry Blues (Alton Delmore)
Lindbergh = White House Blues
From Baltimore to Washington = Cannon Ball Blues (Carter Family)
Grand Coulee Dam/Farmer Labor Train = Wabash Cannonball
New York Town = One Dime Blues (Blind Lemon Jefferson), though it's more a cover than a new composition
