My dad taught me a song as a child that he sang during the depression. It is very close to the lyrics of Uncle Dave Macon.

Verse 4 was different. He taught me the following lyrics.
      I bought some biscuits for my dog
      and laid them on the shelf
      Times got so hard, I shot the dog
      and ate them up myself.

   An additonal verse was this one.
       I heard three little birdies sneeze
       Way high up in a tree
       I know why they were sneezing
       They had no BVD's.

    This is the first verse he taught me.
