That’s a great suggestion, but English and French are just what were in the
snippet I got from the Lilypond manual. We’re actually singing in English and
Español. So I could do “Eng.” and “Esp.”, but I’m worried that abbreviations
would be more confusing than helpful.

I had to add \override StanzaNumber.Y-offset =
#ly:side-position-interface::y-aligned-side in order for the stanza text to not
overlap the lyrics. And I did’t like the way it looked at first. But it’s
grown on me. I’ll probably play with it some more.

This does what I was looking for. Thanks for all your help! I see your point
about overlapping ink. I suspect that in practice it won’t be much of an
issue. And I can always set the StanzaNumber.Y-extent to put some vertical
padding between the Stanza and what ever is above it. Definitely workable.
That said, now that I’ve got what I want, I’m not really happy with it. It
looks very busy visually and feels more confusing than helpful. I’m thinking
that your idea for right-aligning the stanzas may be the more fruitful
direction to pursue.
Thanks again!
David
