This is done with Capo on the Second Fret.

   G                      Em
Oh where, oh where can my baby be
C                      D
The lord took her away from me 
G                        Em
shes gone to heaven so i gotta be good
C                           D
so i can see my baby when i leave this world

its basically the same 4 chords throughout the entire song, just
keep repeating the order even through the verses and chorus
