Blue Danube performing "Du Bist Musik" ("You Are Music"), the Austrian entry at the 1980 Eurovision Song Contest
Trivia: The lead singer here is Marty Brem, who would also represent Austria next year with one of the oddest and most surreal stage acts to ever grace the ESC stage (and that says something!). Incidentally, by a strange coincidence he opened the contest in both years!
In memory of lugogaliza's account... ;-)
