The "Farmyard Song" (Roud number 544) is a cumulative song about farm animals, originating in the British Isles and also known in North America.

It is known by various titles, such as:

• "I Bought Me a Cat"
• "The Green Tree"^[1]
• "The Barnyard Song"^[2][3]

In the first verse, the narrator tells of buying or having a cat, horse or other animal, feeding them under a tree, and the call the animal makes. Each subsequent verse introduces a new animal, then repeats the calls of the animals from previous verses.

There were several versions known in the Thames Valley in the early part of the 20th century.^[4] A version collected in Bampton, Oxfordshire around 1916 began as follows:

The very first thing my mother bought me,
It was a hen, you may plainly see;
And every time I fed my hen,
I fed her under the tree.

My hen went chick-chack,
My cock went cock-a-te-too;
Here's luck to all my cocks and hens,
And my cock-a-doodle-do.^[4]

Musicologists Loraine Wyman and Howard Brockway collected "The Barnyard Song" in Kentucky in 1916.^{[5]: 5 [2]} This version began,

I had a cat and the cat pleased me,
I fed my cat under yonder tree.
Cat goes fiddle-i-fee.^[2]

Some American variants are not cumulative, but instead group all the animal calls together at the end of the song.^[3]
