[mxsfbcll] Back in the USSR

Ivan is the Russian version of John.  (curiously, i -> j, u -> v results in Spanish Juan.)

Pavel is the Russian version of Paul.

Yuri and Yegor/Egor (but not Igor) are the Russian versions of George.

there is no common Russian version of Richard/Ringo.  (coincidentally, he had quit the Beatles during this song).
