There's a sound sample of this at Barnes & Noble, too:

CHOO'N GUM
Curtis/Mizzy

My mom gave me a nickel to buy a pickle,
But I didn't buy a pickle. I bought some choo'n gum.

CHORUS1: Chew, chew, chew choo'n gum, how I love choo'n gum!
Well, I'm crazy over choo'n gum. I chew, chew, chew.

My aunt gave me a quarter for soda water,
But I didn't buy no water. I bought some choo'n gum.

CHORUS2: Chew, chew, chew choo'n gum, how I love choo'n gum!
Well, I'm crazy over choo'n gum. What can I do?

I chew all day, the way it seems.
I'm even blowing bubbles in my dreams.

My pop gave me a dollar to buy a collar.
Well, you should have heard him holler when I bought choo'n gum. CHORUS1

[As recorded by Dean Martin, 1950. Also recorded by The Andrews Sisters and by Teresa Brewer.]
