On this day July 17, 1975

A Russian language version of Conway Twitty’s 1970 hit, “Hello Darlin'” was broadcast to a worldwide audience as part of the Apollo-Soyuz Test Project. The song, which in Russian was called “Privet Radost,” was seen as a “gesture of goodwill” from the Apollo crew to the Soviet Union’s Soyuz crew. Twitty had worked with a language professor from the University of Oklahoma to record the phonetic Russian version of the song.
