The Twelve Days of Christmas
You are encouraged to solve this task according to the task description, using any language you may know.
Write a program that outputs the lyrics of the Christmas carol The Twelve Days of Christmas. The lyrics can be found here. (You must reproduce the words in the correct order, but case, format, and punctuation are left to your discretion.)
- Cf
ActionScript
This program outputs the lyrics to a TextField object. The text field can be scrolled using the mouse wheel (Windows only) or by using the up/down arrow keys on the keyboard.

Racket
This version:
- doesn't capitalise the word Twelfth
- capitalises the French (in French hen)
- capitalised True Love as it may save me a lot of grief when I get home.
- British Variant: changes golden to go-old rings. Anyone who still has enough breath left to sing the second syllable after sustaining the first syllable of golden simply wasn't making enough effort in the first place.
- British Variant: capitalises FIVE GO-OLD RINGS since it needs to be sung at top volume. If you want to change this back; the source is there. But I guarantee you won't have as much fun singing it.
