Lavender's blue dilly dilly

Lavender's blue, dilly dilly, lavender's green,
When I am king, dilly, dilly, you shall be queen.
Who told you so, dilly, dilly, who told you so? '
Twas my own heart, dilly, dilly, that told me so.
(English folk song and nursery rhyme dating to the seventeenth century)

A hit version of the song, was sung by Burl Ives
