We have ideas about what you should do, but they are largely untested.  I
hope people can step back a bit and say, "What can we do with this site?"
in a positive vein.

Links to a static display of the words for the song is one thing.

It is also possible to play the words on the screen as captions in time
with the music.  Using the SMIL format and the Real Networks G2 player that
would play.  

WGBH has a tool under development (beta versions are available) which helps
in creating the caption tracks.  

If this is a bit daunting we should maybe recruit in EO for volunteers to
help you with the captioning of the material.

This stuff is not widely deployed.  There is some at the Able channel.  So
this is not stuff "obviously you should be doing now."  But perhaps by
using the network we can get you help to make your site a
leading-technology example and we can point others at it.  It would be
great to do it with something the kids put up of their own singing.
