OK here we go.....

Rasti rasti moj zeleni bore, (grow grow my green pine),
Da se penjem tebe o vrhove,(that i could climb up to your top),
Pa da ogledam dole niz drumove,(and to look down to the roads),
Pokraj druma zeleni se trava, (at the side of a road is a green grass),
Tu mi dragi na duseku spava. (there is my sweetheart sleeping on a mattress).
It's pretty hard to translate it from serbian to einglish but i try my best !
Glad you like the song! Peace!
