Theater (song)
"Theater" was the German entry in the Eurovision Song Contest 1980, performed in German by Katja Ebstein.
This was Ebstein's third Eurovision entry; she had represented Germany in 1970 and 1971, with "Wunder gibt es immer wieder" and "Diese Welt"
respectively, both times finishing in 3rd position.
The song was performed twelfth on the night (following Norway's Sverre Kjelsberg & Mattis Hætta with "Sámiid Ædnan" and preceding the United Kingdom's Prima Donna with "Love Enough For Two").
At the close of voting, it had received 128 points, placing 2nd in a field of 19.
The song is a Ralph Siegel-Bernd Meinunger collaboration, with Ebstein singing about the manner in which clowns have to mask their true feelings when performing on stage - a situation which is said to be true of all performers.
The four backing singers were dressed as clowns and Ralph Siegel played the piano on stage wearing gloves with small clowns on the fingers.
Ebstein also recorded the song in English (as "It's Showtime"), French ("Théâtre") and Italian ("Teatro").
The song was succeeded as German representative at the 1981 Contest by Lena Valaitis with "Johnny Blue".
