When, in the 1930s, Auden was teaching at The Downs School, he decided that the students should perform a musical, so he wrote the lyrics, composed the music, and directed it. One of the lyrics goes like this:
I've the face of an angel
I've got round blue eyes
And if you knew the things I do
It would cause you some surprise
But when ignorance is bliss my dears
It's folly to be wise
