The other tab for this was awful, so I made my own. It sounds best to me to use a Bar 
chord for C (C:335553) and Bb(Bb:113331)but an open C chord works almost as well.

When strumming this song it's best to let it ring for the words and then do a rhythmic 
DOWN -- DOWN -- DOWN --- DOWN UP DOWN, slightly lifting your fingers from the fret board 
between strums.

Seeing as they're bar chords, you don't really need a capo to change the pitch, and I'm 
not exactly sure what key it's in. But this one works well for most vocal ranges.

C - B - C


C                              [C] B C
I know a girl who's tough but sweet
[C]                             [C] B C
She's so fine, she can't be beat
[C]                       [C] B C
Got everything that I desire
[C]                      [C] B C
Sets the summer sun on fire

And continue that for the whole song.

Chorus:
I want Candy
I want Candy

Verse 2:
Ought to see her with her hair hung down
Ain't no finer girl in town
Candy's just what the doctor ordered
She?s so sweet, she makes my mouth water


Chorus:
I want Candy
I want Candy


Ohhh, I want Candy, Ohhh


C
Hey

I want Candy, Candy, I want Candy

C
Her hair hang down
Hey, Hey, Hey, Hey

Verse 3:
Candy on the beach, there's nothing better
But I like Candy when it's wrapped in a sweater
Some day soon I'll make you mine,
Then I'll have Candy all the time


Chorus:
I want Candy
I want Candy

I want Candy
I want Candy

C
Yehh
Ohh
Hey, Hey, Hey, Hey, Hey, Hey
I want Candy
Ohh, yeehh
Ohh, yeehh
Want Candy
I want Candy
