An hour long documentary program by Leslie Woodhead "How the Beatles Rocked the Kremlin" has been showing on PBS this month. PBS Thirteen has a good discussion and link to watch the full feature. BBC4 still has a review, but the program was taken down. Russia Watch has an article translated to Russian. There are plenty more places to torrent etc., but do at your own risk.
I found the program fascinating! I grew up with the Beatles all around me from my older brother and sister. When my mother was in the hospital giving birth to me, my sister sent a note saying "WOCB (radio on Cape Cod then) has gone all Beatles". A few parts are quite funny, like the mother in Minsk. Curious what your reactions are if you have seen it and, what the Hell, it's free to watch now!
