Concerning the Russian credits, I see no particular problem except the need to switch things a bit to be in name/patronym/surname order, e.g. Boris Ivanovich Fomin. Missing lyricist for Dorogoi Dlinnoyu should be Konstantin Nikolaevich Podrevskii according to the wiki but
it also mentions there's another version of the lyrics by Pavel German.
I think I hear this part right at the beginning
here
so that's Podrevskii
