providing a link to the words would help. Ideally they would be in a format
where they are synchronised with the text (one way to do this is to use SMIL,
so the words can be included as captions). I think if you can do these two
things you have met the requirements of checkpoints 1.1 and 1.4, which are
the two relevant checkpoints for level-A accessibility in this
case. Identifying clearly what the links are too (for example by using a
title attribute to provide explanation of the link:

  <a href="some/caption" title="captions for the song hey-nonny-no"><img
  src="something" alt="captions"></a>

would also be good. (I forget the checkpoint number). Copyright is copyright
- if you are reproducing the words you need to meet copyright obligations.
(If you are linking to them, it is clear that you are not claiming them as
anything but the work/proprety of the site to thich you are linkng, then you
need not worry).

  	Excuse my denseness. We just got an Internet site last week for the school
  I work at. I've known it was coming, and have had bursts of ideas on the
  brain for weeks now. One was inspired by finding a site: Famous Americans:
  Pictures and music by Mrs. Eberle's 2nd grade class (Washington, Jefferson,
  Lincoln, Tubmam, Anthony, King)
  on which 2nd graders sing songs about each of the pictured history people.
  There is no text other than the names under the pictures which serve as
  links to the music. (I would have loved to have found the words to some of
  the songs, but I figured it was more than the kids could handle and the
  teacher saved some for another year... 
  	Anyway, one of my first grade classes, weekly practices "He's Got the
  Whole World In His Hands" until we get a mic in the new lab so they can
  begin to record and edit the piece. 
  	If I am to exemplify "accessibility" to other elementary teachers making
  web pages in their classses, is it enough that I add a text to the page or
  to a link to page of the words? Do I need to include a copy of the musical
  notation? Would I be required to obtain a copyright to include the musical
  notation if that's necessary or usable to the hearing impaired (e.g.)? 
  	The website is "free" educational website for schools under the name of
  Family Education. I get to the site at: http://myschool.com 
  I attended the training last week, and noted, tho the presenters were both
  from Boston, and my ears have been long-trained to the slower pace of
  southern speakers, I don't think I heard any mention of accessibility, tho
  the trainers said we could only put one graphic on per page, I found out
  over the weekend, that I could put a page of graphics (about 12), with a
  background, as long as I store the graphics and background on an off-site
  server ... and I'm anxious to put up a web page with sound on it.... But I
  do want to do it right. But what is right? I try to read up on and and end
  up confused.... Again excuse my denseness.....
