Some of the information presented as "fact" is comprised of myths and legends. For, example, "Silent Night" is reported as being a rushed composition due to the panic caused because the church organ wouldn't play. The substitute composition would be for guitar. (As if other existing compositions could not be adapted for guitar.) Also, "The 12 Days of Christmas" are alleged to be some sort of secret catechism. Do the research, you will find it is not true. Very disappointing book that cannot be trusted. You'll have to spend all your time sorting out what is fact and what is fiction instead of just enjoying the read.
