Out of curiosity I looked up the soviet national anthem and there was a 1944 version, and a 1977 version. In the 1977 version, Stalin's name had been taken out completely and only Lenin was included. Why is this?

It was removed during a process called De-Stalinization which kicked off in 1956 by Nikita Khrushchev, it was to bring the Soviet Union back to Leninist beginnings. They did a bunch of other things to remove Stalin from being a pillar of communism, it did have some negative ramifications for the Union though with Hungary and Poland revolting against soviet control.
