We sure do, and I wrote it for her myself. It's sung to an old folk tune called, "Sweet Molly of Pike." I'll just quote the first verse here. To see the whole thing you'll have to click the link to my novel on my profile page.
I sing this to Daizy whenever she drives too fast (which is frequently). She's not your average little old lady. (Well, her name's Lynne, really. I only call her Daizy while I'm being Dozy.)
"I sing of a driver who's known to the cops, She never slows down, and of course never stops, She speeds down the road when she goes for a spin And no-one can catch her, she's called Leadfoot Lynne."
