Looking for a recording of a song from your choir? There may be a recording link on your choir's webpage as well.  A great place to find recordings of many pieces is: http://listeninglab.stantons.com  You can search by composer, arranger, song title, publisher, catalog #, or classification - i.e. secular songs for winter.
If you can't find a recording of a choir song here, go to: http://listeninglab.stantons.com and type in the title. There might be a full recording or an excerpt of your song.
