Sing a song o' sixpence, a handful of rye,
Four-and-twenty blackbirds baked in a pie;
When the pie was opened the birds began to sing,
Was not that a dainty dish to set before the King?
If you have never heard the legend of Gilligren and the King's pie, you will scarcely understand the above verse; so I will tell you the whole story, and then you will be able to better appreciate the rhyme.
