Russians have a long history with RockNRoll. There has been a discussion amongst historians as to the influence of the Beatles on the Soviet boomers, and the Soviet reaction to them. They were banned from legitimate sales in the former USSR until around 1978, but Soviet kids idolized them, bootlegging millions of copies of Beatles songs recorded from Radio Free Europe, and Radio Luxemburg, which were a hot commodity amongst Soviet youth despite severe sanctions for being caught with copies.
I saw a brilliant documentary called "How the Beatles Rocked the Soviet Union", about the phenomenon. Beatlemania was alive and growing in the USSR, fully ten years after the breakup of the band. A lot of the "aged" rockers were from that group that defied Soviet authority by listening to Beatles tunes.
The hypothesis is that this common nose-thumbing at Soviet authority in the mid-sixties to mid-seventies allowed Soviet youth to breathe the fresh air of freedom at a time when freedom was a scarce commodity in that place. Even Gorbachev, the first "next-generation" premier, professed his love of Beatles music, from the time of his youth.
The old guy is one of those Soviet Beatlemaniacs, I am certain.
