“Old MacDonald had a farm….E-I-E-I-O!” You can’t help but finish this beloved nursery rhyme that has been around since the early 1900s. The earliest version of this song came out in 1917 where the line originally said, “Old MacDougal had a farm in Ohio-i-o,” eventually changing to the familiar song of today. Enjoy Old MacDonald’s farm as you find his farm animals, the sounds they make, and maybe a few hidden letters in Eric’s painting of Old MacDonald.
