This CD set contains many of the song titles you'll recall from childhood. The problem is, the song lyrics are inexplicably altered. For example, "Twinkle twinkle little bat, how I wonder where you're at. Like a tea tray in the sky..." I've never seen a bat twinkle, but then I've not seen many bats. My husband and I hate this CD set. But, it does quiet down our 18 month old daughter, perhaps because the music is sung by children.
