"Sitting on Top of the World" (also rendered as "Sittin' on Top of the World") is a folk-blues song written by Walter Vinson and Lonnie Chatmon, core members of the Mississippi Sheiks, a popular country blues band of the 1930s. Walter Vinson claimed to have composed “Sitting on Top of the World” one morning after playing a white dance in Greenwood, Mississippi.

The song was first recorded by the Mississippi Sheiks in 1930 (on the Okeh label, No. 8784), became a popular cross-over hit for the band, and was inducted into the Grammy Hall of Fame in 2008.

Was all the summer, and all the fall
Just tryin' to find my, little Lenore
But now she's gone, I don't worry
'Cause I'm sitting on top of the world

Was in the spring, one summer day
Just when she left me, she's gone to stay
But now she's gone, I don't worry
I'm sitting on top of the world

Then you come here runnin'
Holdin' up your hand
Can get me a woman
Quick as you can get a man
But now she's gone, I don't worry
I'm sitting on top of the world

(Instrumental)

It have been days
I didn't know your name
Why should I worry and prayer in vain?
But now she's gone, I don't worry
I'm sitting on top of the world

Goin' to the station, down in the yard
Gon' get me a freight train
Worked some, got hard
But now she's gone, I don't worry
I'm sitting on top of the world

The lonesome days, they have gone by
Why should you beg me and say goodbye?
But now she's gone, I don't worry
I'm sitting on top of the world
