It's hard to write down the timing of the song but listen to it and you'll get it

This is the main part (and Intro), so when I write 'D', it means go back to playing this:

    D              Dsus4   
e|--2-2-2-2-2--2-2-2-3-2-|
B|--3-3-3-3-3--3-3-3-3-3-|
G|--2-2-2-2-2--2-2-2-2-2-|
D|--0-0-0-0-0--0-0-0-0-0-|

D
Baby I wanna walk you home
Em                        D
Oh baby I wanna walk you home
Em
There's a shadow in the basement
        Am                D
And I'm scared to sleep alone
D
Baby doesn't everybody weep
Em
Oh baby doesn't everybody weep
Em                    
I'd slide up there beside you
       Am                   D   
But my nightmare's oh too steep
D          Em
Yeah

D
Baby I wanna buy you a Cadillac
Em
Oh Baby I wanna buy you a Cadillac
Em             
I bought it with my song
             Am                         D       
But you say that you're gonna give it back
D           Em
Yeah

D
Baby I love you baby
Em
I love you baby 
            D
I love you baby
D            
I love you baby
D
I love you baby
