Hi, David -
Interesting song. I wonder if it was Czech first, or if the English version is the original. This version uses Leonard Cohen's "Hallelujah" as a chorus, but the verses aren't related to the Cohen song.

THREE TREES There were 3 trees upon a hill and they spoke to The whispering breeze They made 3 wishes upon the hill and the wishes They made were these The first tree wished he could be a fine bed Fit for a king to lie on he said The second a galleon wanted to be To carry a king way over the sea I am what I am I be what I be That’s how it is so said the third tree I have only one wish that I would wish on And that is to be remembered long after I’m gone          Hallelujah        Aleluja          A woodman came by he fell the first tree Oh now a fine royal bed I will be But was it in scorn or was it in anger He found himself fashioned into a manger          Hallelujah        Aleluja          The second tree groaned as he fell to the ground Oh now a galleon soon I’ll be bound But was it a miracle he turned out to be A boat for a fisherman on galilee          Hallelujah        Aleluja          The third tree was left he was left all alone Still he remained and still growing on Till a’ branches a’ torn and twigs all a toss He found himself fashioned into a cross Though he was rough hewn it was his destiny To be the sign for all men to see And the wind from the valley kept murmUring on You will be remembered long after you’re gone

Tri stromy Byly tri stromy, na kopci promlouvaly k šumícímu vánku vyslovily tri prání, tam na kopci a ta tri prání která vyslovily, byla tato První strom si prál, aby byl drahá postel hodna krále k odpocinku, to rekl ten strom Druhý strom galéra chtel být aby prevážela krále cestou pres more Já jsem, co jsem, at jsem, co jsem tak to je, tak pravil tretí strom mám jen jedno prání, vždy si budu prát abych nebyl zapomenut ješte dlouho poté, až tu nebudu          Hallelujah        Aleluja          Drvoštep tam prišel, povalil první strom ach, drahá královská postel ted budu ale at z neúcty ci zloby to bylo jen k výrobe koryta se hodil          Hallelujah        Aleluja          Ten druhý strom zasténal, když padl k zemi ach, ted galéra brzy musím být ale div to byl, nejinak dopadl než lodka pro rybáre na portálu kaple          Hallelujah        Aleluja          Tretí strom byl ponechán, byl ponechán zcela osamocen stále zustával a stále vzrustal až se jeho vetve odlomily a vetvicky kolem poházeny byly pak ten strom k výrobe kríže posloužil ac byl hrube osekán, jeho osudem bylo být znamením, které celé lidstvo spatrí A vítr z údolí stále šeptal nebudeš zapomenut ješte dlouho poté, až tu nebudeš

I've heard this song in English occasionally. Wish I could remember where.
