I’m 65 years old. When my boys were growing up I played these cassette tapes (yes years ago!) Together we memorized all the verses. They got a token for each verse they could say/sing successfully. We collected them in jars. And when vacation came: they cashed in their tokens (poker chips) for money. Even today when I read my Bible the song will pop into my head! All these years later! i recommend this series to everyone. I gave the CD set to my granddaughters.
