I derived this tab from a version of this popular old nursery rhyme on an old children's show from  
1974 called Bagpuss. It is a more upbeat folk version than most other variations but I think it sounds  
better this way. And also to fit the theme of this song, I have posted the tab for the mandolin as well!  
This is only the main melody, I haven't figured out any extra parts yet.

If you don't like moving your hand up and down the neck that quickly then try this lower octave version:
