Karen,I'm A Little Cookie is such asong as you are looking for. So is a song by Si Kahn similar to People like you but boy the name escapes me now.
In my work as a designer of equipment and living paces for people with disabilities I find that the "C" word is not always out of style. Like many of the dreaded PC phrases it is situational. Many Viet Nam era vets who are wounded and disabled call them selves and other vets crips. So do some disabled cops. I take a riffle of shit if I call them otherwise.
I've learned that good and respectful manners and not PC words are more important than just talking an approved language.
As a builder I am frequently placing cripples under window ledges. All that means is short 2x4's that don't go to the ceiling. Imagine the can of worms I'd open if I called them disabled studs?
