My Ding a Ling

I'm sure that the song is played in E:

so the chords are E to A to B to E all the song repeated.

E chord:
E|--------| 
B|--------| 
G|--1-----| 
D|--2-----| 
A|--2-----| 
E|--------| 

A chord:
E|--------| 
B|--2-----| 
G|--2-----| 
D|--2-----| 
A|--------| 
E|--------| 

B chord:
E|--2-----| 
B|--4-----| 
G|--4-----| 
D|--4-----| 
A|--2-----| 
E|--------| 

to make it more interesting (chuck does so) play this at the beginning:
E|---------------------------------| 
B|-----0-----0-----0---------------| 
G|-----1-----1-----1---------------| 
D|--2-----------2------------1--1--| 
A|--------2------------2--4--------| 
E|---------------------------------| 

when the text comes in play this:

   E           A               B                    E
E|------------------------------------------------------------------| 
B|-----0-----0-----2-----2-----4-----4-----4-----4-----0-----0------| 
G|-----1-----1-----2-----2-----4-----4-----4-----4-----1-----1------| 
D|--2-----------2-----------------4-----------4-----2---------------| 
A|--------2-----------0-----2-----------2-----------------2---------| 
E|------------------------------------------------------------------| 

    When I was  a little biddy boy, my grandmother bought me a
(make a little break to play the B part, Chuck does, too, because it's a 4/4 beat) cute little 
toy
