I've always liked, "It was a dark and stormy night..."
Ducking, running, dodging, and laughing my head off....
Really yes I liken the first line of a book to the first line of a song. If you don't like it you stop listening. Here are some of the first lines of my most popular songs. (I'm a self published singer/songwriter/storyteller)
"It's the second month of Viking, there's one more month to go."
"Young child, watching, do you understand?"
"Far o're this world I wandered, seen lands of ancient fame."
"The white rose stand for purity, it's petals brilliant white."
"From the shores of Jotenheim where giants walk the land."
"Sing to me oh cold north wind, of the lands that I know well."
