Russian and Soviet Music

Christopher, I am just listening to your uploads of the Grechaninov excerpts from Dobrynya Nikitich.
Something is wrong with the Act I introduction: after 45 seconds there is a big silent gap of about 1 min 40 sec.
I tried to cut the silence but the bits did not join, so the music must have been going on.
I have downloaded the file two times but the same problem occurs. Sorry.
