Can anyone one help me figure out the chord changes to this Dr. Suess Green and Eggs and Ham into song? I think the first few chords may be E C#m A B???

Here is a You Tube link to the animation and song. It runs from 0.09 to 0.44 secs at the start. The Cat in the Hat is singing it!

The parents at my kid's school have to put on a show for the kids - we are doing Green Eggs and Ham and I'm thinking about adding this into it.

Thanks
