In that Rhymes and Reasons are songs, not poems, I’ve left them in the accepted patterns necessary to set them to music. There may be some repetition but rare is the song sang in its entirety without repeating verses or choruses especially, what is now considered the chorus. The earlier songs were primarily AABA or ABAC patterns which were the norm back then. As patterns evolved into the more contemporary verse-chorus mode, I’d suspect that happened because repetition of the chorus allows for more rousing concert finales in which audience might be tempted to sing along.
