Взяв би я бандуру
It shares a melody with "Hymn of the Fallen Legionaries" - Simion Lefter. The melody was almost definitely copied by Lefter, as the "Взяв би я бандуру" sheet music was published as early as 1927 in New York, the same year the Legionaries were founded. The modern lyrics were published as early as 1921 (in an УСС dictionary) and there are records of similar songs going back into the mid 1800s. The modern melody works perfectly with those older lyrics.
