Almost by accident, the Austrian band Opus found themselves in the UK Top 10 in 1985 thanks to an innocuous singalong number made memorable by the crowd that was joining in.
Live Is Life was a brand new track that the band performed at a gig in the Austrian town of Oberwart in 1984. The instant hook of “na-na na-na na” got such a response from the audience that the audio was snicked off the recording and issued worldwide as a single in June 1985. UK DJs began to play it, and the song worked its way into the Top 40, eventually peaking at No.6.
