Donovan - Jabberwocky Chords & Tabs

I made this because I think the other version is all weird and doesn't sound right, 
except for maybe the tabs. But I came here looking for chords, so apart from complaining, 
this is my interpretation. Correct me if I'm wrong!

I strum along to the words, and just play a bit with up- and downstrokes. Listen to the 
song a bit and you'll find that this is generally where the chords are at. These Chords 
are basically the same troughout the whole song.

Dm                      C       Dm
'Twas brillig, and the slithy toves
    A#        A       G     F
Did gyre and gimble in the wabe.
Dm                      C       Dm
All mimsey were the borogroves
          A#                A
And the mome raths outgrabe.

Dm                      C       Dm
"Beware the Jabberwock, my son!
    A#        A       G     F
The jaws that bite, the claws that catch!
Dm                      C       Dm
Beware the Jubjubb bird, and shun
          A#                A
The frumious Bandersnatch!"

Dm                      C       Dm
He took his vorpal sword in hand:
    A#        A       G     F
Long time the manxome foe he sought
Dm                      C       Dm
So rested he by the Tumtum tree,
          A#                A
And stood awhile in thought.

Dm                      C       Dm
And as in uffish thought he stood,
    A#        A       G     F
The Jabberwock with eyes if flame
Dm                      C       Dm
Came whiffling through the tulgeywood
          A#                A
And burbled as it came.

Dm                      C       Dm
One, two! One, two! And through and through
    A#        A       G     F
The vorpal blade went sniker-snack!
Dm                      C       Dm
He left it dead, and with its head
          A#                A
He went galumphing back.

Dm                      C       Dm
"And hast thou slain the Jabberwock?
    A#        A       G     F
Come to my arms, my beamish boy!
Dm                      C       Dm
O frabjous day! Callooy, callay!"
          A#                A
He chortled in his joy.

Dm                      C       Dm
'Twas brillig, and the slithy toves
    A#        A       G     F
Did gyre and gimble in the wabe.
Dm                      C       Dm
All mimsey were the borogroves
          A#                A
And the mome raths outgrabe.
