I think it's a good idea to have existing singing communities print up their own song lyrics in a book form. It doesn't have to be "pro".

Each singing group likes its own songs. RUS serves as a model.

I also think it would be useful to have songs categorized. Not all folks like to sing just
folk songs. (Whatever they are).

Where Mary and I sing every Thursday, they like a variety of songs. Many remember songs from the past that they used to hear on the radio.

Sometimes a conversation will trigger a song. We go into it. Other times, we look at
lyrics for reference on some songs.

When people know how to contribute to a singing session, it doesn't matter whether
there are song books or not.
