All Cows Eat Grass: Discuss.

When I was learning to play the piano, All Cows Eat Grass was the mnemonic I was taught for remembering the notes - A, C, E, G -in the spaces of the bass clef. I expect music students are still taught that. - The notes are still the same. The mnemonic still works. But is the former axiom still true? In the modern world in which agribusiness has taken the place of so much traditional farming, to get the names of the notes right, maybe we should change the mnemonic to All Cows Eat Grain.
