Sometimes I sing to myself, in my head; something lugubrious, mournful, Presbyterian:  

Amazing grace, how sweet the sound

Could save a wretch like me,

Who once was lost, but now am found,

Was bound, but now am free.  

I don’t know if the words are right. I can’t remember. Such songs are not sung anymore in public, especially the ones that use words like free. They are considered too dangerous. They belong to outlawed sects.

–The Handmaid’s Tale by Margaret Atwood
