My Grandfather sang a great song that none of us can remember all of the lyrics to. I have part of the song, can you help me find the lyrics to the rest of it?

Oh Possum in a 'simmon tree,
a lookin down, way down on me
Fast by de tail that critter hung,
and to himself, did sing this song

Oh Masta sent me to da spring
To get some water mid a sling,
My foot slipped out and I slid in
And I crawled out and begin to sing..

Oh I jus come from da white folks house
sing song Polly want a kimee O
a something in a bucket of souce
sing song Polly want a kimee O

Oh, Keemo Kimo Va you da,
sing song Polly want a Kimee O
I Put some pepper in my Dad's snuff box,
Sing song Polly want a Kimee O

a rump a thump arupma thumpa sing song Polly want a Kimee O
