Mungo Jerry:
"If her daddy's rich, take her out for a meal
If her daddy's poor, just do what you feel "
Which explains why the Zombies tried to find out, I guess.
"What's your name? Who's your daddy?
Is he rich like me?"
Someone annotated these lines in Dion's "Wanderer"
And when she asks me which one I love the best
I tear open my shirt and I show her "Rosie" on my chest
"‘Rosie’ is most probably referencing a tattoo of a compass rose on his chest, a symbol of his nomadic tendency."
Can't say that interpretation ever occurred to me 🤨
