"The Farmer and the Cowman" is a song composed by Richard Rodgers and with lyrics by Oscar Hammerstein II for their 1943 musical Oklahoma!.
In various versions of Oklahoma!, the singing parts for Ike, Andrew, and Aunt Eller have been swapped.
This number, and the scene itself, takes place at the Skidmore Ranch, where the box social follows after the song.
[1] Carnes, Aunt Eller and Ike act as peacemakers and attempt to reconcile the two sides.
Aunt Eller then shoots a gun in the air to stop the fighting, and conducts both groups – preaching peace with the lyrics of the song, but threatening violence.
