Speaking of references to Jekyll and Hyde in song, check out "You Can't Teach a Woman How to Drink" by the Happy Schnapps Combo (written by J.Krueger):

Well I took my gal out to dinner, it was such an enjoyable night
She said I was the best looking guy in the place and I said "Honey, you're right"
Pick up the check, said "What the heck, let's stop for a drink somewhere"
But when it comes to women and liquor, lord let the bar beware

She had a couple drinks, couple drinks and she started to cry
I came in da bar with Dr.Jekyll, now I'm sittin' here with Mrs.Hyde
Oh how can we come so far in this world, how can we come so far in this world
Put a man on the moon, make computers that think
But you can't teach a woman how to drink

... etc
