Una Mosca

I asked Guthrie's teacher about the words to the song he loves. Turns out it really is Spanish:

Una mosca pegada a la pared.
Una mosca pegada a la pared.
Una mosca
Una mosca
Una mosca pegada a la pared.

"A fly is stuck to the wall"

Then of course, they sing it w/ all the vowels - turning it into complete nonsense. I remember doing this all growing up with the song "I like to eat, eat, eat, Apples and Bananas."
