Code Golf: Print the entire "12 Days of Christmas" song in the fewest lines of code

Print all 12 verses of the popular holiday song.

By 12 verses I mean the repetition of each line as is sung in the song, ie

Verse One: On the first day of Christmas my true love gave to me a partridge in a pear tree.

Verse Two On the second day of Christmas my true love gave to me two turtle doves and a partridge in a pear tree.

...

Verse N: On the nth day of Christmas my true love gave to me (Verse N-1 without the first line) (line added in verse N)

Common Lisp:

(mapc #'princ
      (reverse (maplist #'(lambda(l)
         (format nil 
            "On the ~:R day of Christmas my true love gave to me~%~{~a~%~}~%" 
                (length l) l)) 
    '("twelve drummers drumming,"
      "eleven pipers piping,"
      "ten lords a-leaping,"
      "nine ladies dancing,"
      "eight maids a-milking,"
      "seven swans a-swimming,"
      "six geese a-laying,"
      "five gold rings,"
      "four calling birds,"
      "three french hens,"
      "two turtle doves, and"
      "a partridge in a pear tree."))))

Edit:

Above is 412 characters if you take out the whitespace.

This one:

(let ((g))
  (dotimes (i 12)
    (format t
        "On the ~:R day of Christmas my true love gave to me~%~{~R ~:*~
         ~[~;~;turtle doves and~;french hens,~;calling birds,~;gold rings,~
         ~;geese a-laying,~;swans a-swimming,~;maids a-milking,~
         ~;ladies dancing,~;lords a-leaping,~;pipers piping,~
         ~;drummers drumming,~]~%~}a partridge in a pear tree~2%"
        (1+ i) g)
    (push (+ i 2) g)))

is 344 characters if you take out whitespace and ~ quoted newlines in the format string:

(let((g))(dotimes(i 12)(format t"On the ~:R day of Christmas my true love gave to me~%~{~R ~:*~[~;~;turtle doves and~;french hens,~;calling birds,~;gold rings,~;geese a-laying,~;swans a-swimming,~;maids a-milking,~;ladies dancing,~;lords a-leaping,~;pipers piping,~;drummers drumming,~]~%~}a partridge in a pear tree~2%"(1+ i)g)(push(+ i 2)g)))

Edit:

It looks like the question has run its course, and the site is nagging me to accept an answer. As far as I can see, this one is the shortest. I'm a little afraid of what the site will do if I accept my own answer - probably award me a Narcissist or Masturbator badge.

You can't accept your own answers. Fair enough. I'll leave it open. Thanks to everyone who responded.
