The French song by Serge Gainsbourg and actress Jane Birkin was deemed too erotic to air on the show.
The song featured hyper-sexualized lyrics and female moaning in the background. It even culminated in an apparent orgasm.
The track caused such a stir that the original label, Fontana, dropped the record, despite it being No. 2 on the charts. Major Minor, a smaller label, later bought the rights to the song, which proceeded to hit No. 1 – a first for any French-language song.
