Looking for Answers about Lillenas A Season For Joy, Unison/2-Part Songbook?

Created especially for unison and 2-part choirs, five songs with narration run about 15 minutes. Built into the vocal arrangements are a few optional voice divisions. These can be arranged however you wish: high voices (male and female) sing the upper while low voices (male and female) sing the lower notes; or ladies sing the top, men sing the bottom (or vice versa); or a few seleted voices sing one note, everyone else sings the bottom.
