Twin Sisters Productions is a local (now) digital media organization, which was founded in 1987 to provide a fresh approach to the old standard nursery songs we all grew up with. Concentrating on old favorites, and inspirational Bibilical themes, today they are entirely digital. These CD/Book sets are out-of-print in the physical sense: if you want the stories, you down load them in PDF format and print them off at home. If you want the songs, you download them and perhaps cut a CD at your computer. The books were released in a second edition, without the plastic bubble on the front cover, the CD inserted in a plastic sleeve pasted down to the inside front board. Today, the downloads cost $9.99 each (plus tax).
