Grace,

There are several methods of finding lyrics.

1 - Listen carefully to the song, over and over. Works much easier now that you can put it onto your computer, and play it over and over.
2 - Pore through the books, until you find it.
3 - Use the various search engines

http://www.google.com
http://www.metacrawler.com
http://www.altavista.digital.com/

Those are three examples of search engines. There are lots more.
