I am once again dipping my foot in the shallow end of the LilyPond.
I added a footnote to the title. It puts the superscript "*" at the end, but then the footnote never appears anywhere. What am I missing? (This isn't for a book or anything fancy like that. And, initially I tried it without \concat as just a single very long line, to the same effect.)
\header { title = \markup { "The Song of the Heather" \footnote "*" \concat { "* This song has been translated by the leading Irish," " Scotch Gaelic, Manx, Welsh, Breton, and Cornish poets" " into their native languages for singing in each Celtic" " country and at Pan-Celtic Festivals." } } }
