Bow your head with great respect and genuflect, genuflect, genuflect
is a line from the Tom Lehrer
song The Vatican Rag
. The song was released after Vatican II
and pokes fun at the Church
for updating Mass
and making it more accessible to the people
On a personal note, my Catholic Grandmother hates this song. She hates that I know all the words to it, and that I have, on occasion, tried to sing it to her when she suggests that I go to church with her.
