I know the forth

I doubt you will be able to find them, since all of them, with the exception of the forth one, are old Russian folk songs, to find the original will be very hard...

P.S. I really like the first one, the words there are so true...

The second one is Israeli version of Rosenbaum's song "Uchili menya otets moi i mat' - lyubit', tak lyubit', strelyat', tak strelyat'..."
