Looking for sheet music/lyrics to a song

Factual Questions
1

My two sisters (PS1 and PS2) are looking to perform “I Feel Sick” from “How to Eat Like a Child” for a musical tryout. Searches on various websites and search engines have proven essentially fruitless. A search on Napster, by the way, just to get the lyrics, turned up nothing. Nothing from the musical, no song like it.

So I appeal to you, O Teeming Millions. Where? Where can I find this piece vital to . . . well, my sisters’ happiness? Do they have to resort to buying the whole musical, or is there even a place where they could get it for free?

There’s a MIDI file here:

Now that you have the MIDI, you can convert it to sheet music. There are various shareware programs that will do that for you, though the results are not always perfect. I use MidiNotate
