Niles Ritter writes: 
I read in a technical book (sorry, can't remember which) that 'Eat Or Be Eaten' was the first CD+G disc published in the US. [actually, this was some time ago, and the book said that it was the *only* CD+G disc published in the US] So I popped it in a CDTV box, and sure enough... The screen gets refreshed every 2-3 seconds, and it does add a dimension to the fun.
