Hi Guys,
Still no takers? More clues:
"One pill makes you larger,
And one pill makes you small,
And the ones that mother gives you,
Don't do anything at all,
Go ask Alice, when she's ten feet tall
And if you go chasing rabbits,
And you know you're going to fall,
Tell 'em a hookah smoking caterpillar,
Has given you the call,
To call Alice, when she was just small"
Hint: this song was used in a very well known movie based on the Vietnam War.
The movie is Platoon.
