I bought a cassette tape of this years ago. My then young children enjoyed it very much. Well, they grew up and I think I gave that tape to my daughter who has her own children now. I'm teaching a midweek class of 1st-4th graders, so I'm ordering it again in the updated format to share with another generation. I've been singing and humming the songs on this CD for many years, and "Don't forget about the earthquake!".
