Ultravox
From Tardis Wiki, the free Doctor Who reference
Ultravox were a pop group in the 1980s, authors of at least the song "Vienna".
Professor Grisenko was a fan of theirs, and listened to their cassettes whilst serving on board the Soviet submarine Firebird. When finding out that Clara Oswald was from the future, he asked her if they break up. (TV: Cold War)
Behind the scenes
Although Clara didn't answer Grisenko's question, in the real world, Ultravox did split up in 1988, 5 years later.
