A childhood belief about hymns

In Sunday School we used to sing a song about "The wise man built his house upon the rock/the foolish man built his house upon the sand."
The chorus said, "The rain came down and the floods came up/and the house on the rock stood firm/and the house on the sand fell flat."
And I used to sing loudly, "THE RAIN CAME DOWN AND THE FUSS CAME UP!!" and I'd picture a crowd of people fussing around outside the houses.
