We are paying our organist and bagpiper and singer to be at our rehearsal. I was under the impression we needed to invite them to the dinner as well but my mom said I probably don't have to. She said she's never been to a rehearsal before where musicians attend the dinner and doesn't think they would want to go with a family they don't know. I'm just wondering what the proper etiquette is because it would be great to save money and not invite to the dinner but I'd rather do the right thing.
