Real Boys' Voices

I read the 6th (2013) edition in the summer of 2018. I finally purchased my own copy to own in the 2006 edition in the autumn of 2018.

Great book, but I just skimmed it. It was preaching to the choir.

I will consider looking up a more recent version, I believe that there was a 7th edition in 2013, not sure if/when there will be a subsequent edition.
