Since "Wind Beneath My Wing's" is my all-time favorite song, I intended to list it. However, you've already ruled that one out.
There is an old Ronnie Millsaps song entitled, "What a Difference You Made in my Life." I can't recall all the lyrics, and it may evolve into another love song, but I do remember this part:
"What a difference you've made in my life,
What a difference you've made in my life
You're my sunshine day and night.
Oh, what a difference you've made
In my life."
There is also a very long American song entitled, "Everyday Heroes." I can only recall a very small part of the lyrics, and I think they make up the chorus because (if memory serves me), the verses describe various everyday heroes and why the songwriter considers them heroes. Here's the bit I remember:
"Cause you know heroes come in every shape and size
Making special sacrifices for others in their lives
No one gives a medal, the world don't know their name
But in some one's eye they're heroes just the some"
I hope some of this is helpful to you because people who help others deserve being honored. Good luck, Billie!
