'Anthem Title' in Raleway but in italic.
'Anthem Composer' and 'Birth/Death dates' immediately after anthem title, in Raleway, but NOT in italic.
'Anthem text' as is
Anthem lyrics source as a new line below Anthem text, in Raleway 9 pt, right-aligned, italic. Prefaced with 'Words: '
If anthem lyrics source is to be found in NEH, Anthem text says "Anthem text at: NEH XXX: First line of hymn", and then no anthem lyrics source.
