If you use the VP catalog you can find books to go along with each card. (It is the number in yellow following the description of each book)
Instead of using the CD that VP publishes with the cards, we use Classical Christian History Songs by Kathy Gentili. She has all five songs (Creation through The Birth of America) on 1 CD. Her songs include card numbers, exact card titles, and dates for each card (VP songs do not).
I ordered the CD directly from her. If you are interested, I can get the ordering info for you.
