This is what they said was the chords on their YouTube video. I tried it out and it 
sounded right so, here's one of the greatest songs on earth.

(Verse 1)
C
Saw her on the sidewalk sellin' lemonade
Am
Her name was Jessica, we were in the third grade
F
She had style, she was cute
G
In her stonewashed jeans and her jelly shoes

C
Within a week a was callin' her my girlfriend
Am
That's when I started to neglect my teddy Rufspin
F
We spent a lot of time talkin' on the phone
G
And watchin' classic films like Home Alone

C
She put Brian Adams on a mixed tape for me
Am
Then in fourth grade she started to ignore me
F
She got into makeup, I got into kickball
G
It was a messy breakup

(Chorus)
Am          F
Red Rover (Red Rover)
C                  G
Me and Jessica are over
Am                      F
She broke my heart and hurt my wrist
C                 G
With her snap bracelet

Am          F
Red Rover (Red Rover)
C                  G
Me and Jessica are over
Am                                   F         G
And I don't think I'll ever fall in love again
                        C
At least not 'till I'm ten

(Verse 2)
C
She asked me to dance at the Halloween party
Am
I was Jake the snake and she was Tanya Harding
F
The next day when I asked her out
G
She said I can't right now I gotta watch full house

C
So pretty soon things got a little messy
Am
She found a new guy, he looked like Uncle Jesse
F
I should've known right from the start
G
While I played Nintendo she played with my heart

C
When we were young we took so much for granted
Am
Like Hootie and the Blowfish and Pluto as a planet
F
She's alone in Wal-Mart

I'm stalkin' her on MySpace
G
She should not have broken my heart

(Chorus)
Am          F
Red Rover (Red Rover)
C                  G
Me and Jessica are over
Am                      F
She broke my heart and made me sick
C          G
With mononucleosis

Am          F
Red Rover (Red Rover)
C                  G
Me and Jessica are over
Am                                   F         G
And I don't think I'll ever fall in love again
                        C
At least not 'till I'm ten
