Seals & Crofts - the soft-rock duo recorded pro-life song called “Unborn Baby”.
Listen to the song at this website or on the internet. Lyrics…

Oh little baby, you'll never cry, nor will you hear a sweet lullaby.
Oh unborn child, if you only knew just what your momma was plannin' to do.
You're still a-clingin' to the tree of life, but soon you'll be cut off before you get ripe.
Oh unborn child, beginning to grow inside your momma, but you'll never know.
Oh tiny bud, that grows in the womb, only to be crushed before you can bloom.
Mama stop! Turn around, go back, think it over.
Now stop, turn around, go back, think it over.
Stop, turn around, go back think it over.
Oh no momma, just let it be. You'll never regret it, just wait and see.
Think of all the great ones who gave everything
That we might have life here, so please bear the pain.
Mama stop! Turn around, go back, think it over.
Now stop, turn around, go back, think it over.
Stop, turn around, go back think it over.
