Elton John and Ray Cooper are playing in a restaurant in the Soviet Union song "I Heard It Through The Grapevine" (written by Norman Whitfield, Barrett Strong).
Perhaps it was the hotel restaurant Pribaltiyskaya to Leningrad (hotel where lived Elton John and Ray Cooper during the Soviet tour in 1979)
21-28 May 1979 Elton John was invited by the Soviet Ministry of Culture and gave 8 concerts in Leningrad and Moscow. Elton John was the first Western rock star, who gave a concert in the Soviet Union during the Cold War.
