We have a most lovely hymn which is sung to the tune of Finlandia. The lyrics are credited to Lloyd Stone and Georgia Harkness.
This is my song, O God of all the nations,
A song of peace for lands afar and mine.
This is my home, the country where my heart is;
here are my hopes, my dreams, my holy shrine;
but other hearts in other lands are beating
with hopes and dreams as true and high as mine.
My country's skies are bluer than the ocean
and sunlight beams on cloverleaf and pine.
But other lands have sunlight too, and clover
and skies are ev'rywhere as blue as mine.
So hear my song, O God of all the nations,
a song of peace for their land and for mine.
This is my prayer, O God of all earth's kingdoms,
your kingdom come; on earth your will be done.
O God, be lifted up till all shall serve you,
and hearts united learn to live as one.
So hear my prayer, O God of all the nations;
myself I give you; let your will be done.
I always look at the hymn tune, meter, and text/music source when singing. Our hymnal has a listing of "Sources of Service Music and Hymns" in the back so it's very easy to where they came from. A quick glance reveals Bach is credited with eight, Beethoven one (Joy of course), Handel one, J Haydn one, M Haydn one, Holst three, Ireland two, Mendelssohn one, Nielsen one, Palestrina one, Purcell one, Schubert three, Schumann one, Sibelius two, Vaughn Williams ELEVEN. Could be more because this print is very small and I may not recognize all composers at name sight (I know John Ireland now only because I'm currently reading a bio of B. Britten).
Of note to Huilin is that eight are based on "Finnish folk tune."
