Karen, in order to interpret mondegreens, you have to have what I call "mairzidoats ears". You have to hear them the way children naturally hear them.

Here goes:

1. (the famous Wildwood Flower)
"I will twine with my mingles of wavy black hair"
"I will twined midst the ringlets of my raven black hair"........ Maude Irving's original
(Also) "The pale emalita and eyes of dark blues)
          "The pale amanita and islips so blue" (no scientific mention of amanita in botanical journals.)

2. "Where the beer and the cantaloupe lay"
    "Where the deer and the antelope play".............Home on the Range

3.   "Free grapes and driving gloves"
      "Free Grace, undying love"...............................Ring Them Charming Bells

4.   (A variation on the Child Ballad, Lord Randal)
      "You picked a fine time to feed me loose eels"
      "You picked a fine time to leave me, Lucille.................Lucille
      (Kinda' fishy and maybe stretching a point)

5.   "You're infectious, blow your nose, honey snuffle Rose."
      "You're confection, goodness knows, Honeysuckle Rose..........Honeysuckle Rose

6.   "My country's misery, three cans of liver tea"
      (You know the rest).............................................................America

7. (for the sacrilegious here)
    "He maketh me to lie down in brown pastures"
      (Not sure this is a mondegreen but I thought funny)
