And my question is - what is the name of music, which starts at:
-17:17
-1:09:57 (this must be 100% soviet, it's a march)
-1:06:48 (choir)

Regards!

I am afraid I can only identify the last one, which is a composition by Robert Schumann called Traumerei/Reverie, you can find it here.

Thank You! That's definetely it! So, we have to find another two music compositions who can help? It's been long long time, when i started finding it.
