I learned "The Farmer is the Man" from one of Wilfried Drygala's songbooks. It is a fine song extolling the farmer and his indispensability. According to the notes I made, this was a popular song with Midwestern farmers in the 1880's i.e. the days of the Farmer's Alliance, the Greenback Party and the founding of the Grange movement.
It's a fine song to sing, quite witty and tuneful. Unfortunately I sing it only rarely.
