Disco was a pop music program that aired in Germany on the ZDF network from 1971 to 1982. It generally aired on the first Saturday of each month at 19:30, each show running 45 minutes. 133 shows were produced. The show was hosted by German actor and comedian Ilja Richter. The show focussed on chart hits current at the time of airing, giving about equal airtime to international pop music and German Schlager. Despite its name, it did not particularly focus on disco music although it featured many disco hits as long as they were chart relevant. (The name of the show was devised before disco as a musical style existed).

Apparently every Disco show from 1973 till 1976 was filmed in Hamburg and then moved to Munich in February 1976.

Programme 54

I Do, I Do, I Do, I Do, I Do - This was the first appearance of the cat costumes on TV although they had been worn the week before for Made in Sweden - For Export. However, as that programme wasn't broadcast until October 1975, this edition of Disco introduced the cat costumes to the world. Presenter was as usual Ilja Richter.
