(Do you know:" Da dada da dada de da")

Apple trees and pear trees were aflower, 
River mist was rising all around. 
Young Katyusha went strolling by the hour 
On the steep banks, 
O'er the rocky ground. 

(Oh, my song, my song of a maiden's [bad word] love, 
To my dear one travel with the sun. 
To the one with whom Katusha knew love, 
Bring my greetings to him, to him one by one.)

By the riverbank she sang a love song 
Of her hero in a distant land. 
Of the one she'd dearly loved for so long, 
Holding tight his letters in her hand. 

(Let him know that I am [bad word] and faithful, 
Let him hear that love song that I send. )
Tell him as he defends our home that, 
 [bad word] Katyusha our love will defend.
