Query: Mostly Simple Melody - with Typos

This book is mostly a basic melody of Christmas carols. I say "mostly" because there are a few typos. In the words, it doesn't matter much because you understand what they are trying to say, and we all pretty much know the words. However, when notes in the melody are written incorrectly, it can really cause difficulty in playing.Good concept for a beginner Christmas book, but they really needed to proof-read once more before publishing.
