This song has haunted my friend for decades, so I’m hoping to surprise her with an answer. Here’s what I know:
The song has these lyrics: “Give a little bit of your heart, and look what you find within.” She has the tune, too, but I don’t know how to write music. It’s slow, and maybe staccato like a xylophone or music box.
She said she thought of it it right after she had watched The Boy Who Could Fly and Mazes and Monsters. Her family immediately recognized it, but no one could place it. The movies were on VHS tapes, but she’s seen both since, and the song is nowhere in them.
She said she thinks it’s most likely from another movie from that era–American movie aimed towards children, out on VHS 25-30 years ago. Possibly a fantasy genre. The song is also likely to be from the opening or ending credits, or maybe in the background. She is pretty certain the characters didn’t sing it.
Someone told her it could be from a LDS commercial but she (and I) can’t find it. She’s also 100% sure it is not the song by Supertramp or the one by Ariana Grande.
