This song is already posted in Bb, but the lyrics for that one are not a version I know of.
Here's the version I know...

-2   -3 4 -4   -4   4   -4 -3
One summer day, she went away
-4   -4   4   -3’ 3   -4     -4 4   3
She gone and left me, she's gone to stay.
-2   -2 -2    -3    3 -3 -3    3 3
But now she's gone, and I can't worry:
-2” -2   3 -3’ 3 -3’-3 -2 -2 -2   -2
Because I'm sitting o-n   top of the world.
-2     -3   4 -4 -4    -4    4    4 4 -3’ -3
Worked all the summer, worked all the fa-l-l
-4 4   4    4 3     4 -4 4 -3’ 3
Had to take Christmas in my overalls.
-2 -2 -2 -3    3 -3 -3    3 -1
But now she gone, and I don't worry
-3’ 3   -3’ 3 -1 -2   -2
Sitting on top of the world.

-2 -2 -3 4   4   -4     -4
Going down to the freight yard,
-4   4 -4   -3     -3
Catch me a freight train.
-4 -4     4   -3’ 3
I’m gon’ leave this town
-4    -4 -4 3 -1
Work done got ha-rd
-2 -2 -2 -3    3 -3 -3    3 -1
But now she gone, but I don't worry
-2” -2   3 -3’ 3 -3’-3 -2 -2 -2   -2
Because I'm sitting o-n   top of the world.
