Eurovision Song Contest 1976

This was the first edition of the contest with an audio track produced in stereo, which was reserved for the radio broadcast of the show. On TV, the transmission was originally made in mono as usual. In 2021, as part of the initiative "Eurovision Again" that was launched during the Covid-19 pandemic, the Dutch channel rescued the stereo audio track from the radio transmission and synchronized it with the video of the TV broadcast, resulting in a brand new stereo version of the show which was released on YouTube for a limited time. The first contest to be originally broadcast on TV with stereo sound was the 1984 edition, although TV channels around Europe wouldn't start broadcasting the show in stereo in a majority of countries up until 1988.

When the host started giving her farewell speech, her microphone was completely switched off and she kept on speaking for almost a whole minute without noticing she wasn't being heard at all. Then, when they brought her a backup microphone, she started over again, but the backup microphone was also switched off from the TV signal, and even though her voice was faintly heard from what other microphones around picked from the auditorium speakers, TV viewers at home were barely able to hear these first words again, until they got the audio fixed after a few seconds.
