I'm pleased to report that I have started adding recordings of me singing songs from the list on my website. The new pages are titled "Vocal" followed by the SONG NAME. My purpose in doing this is to help people learn songs, especially if they don't know how to read music. The recordings are not CD quality but are adequate for this task. (I used my phone to record and export the music files).
There are some pieces for choir that are too difficult to record by myself. However, for a few songs I have recorded a SOPRANO part (with me singing an octave below the written notes) and a TENOR part, with me singing the tenor part as written).
Once you have used the Vocal part to learn a song, you can sing along with the MP3 backtrack at the proper tempo, using the printed scores for the words.
