In 1977, a strike by BBC cameramen led to the contest being blacked out on TV, although the show went ahead and the audio portion was later broadcast on BBC Radio 2. The TV programme has never been broadcast and is not listed in the BBC archives, yet it was transmitted to the various regional juries in BBC studios around the country, in order for them to cast their votes. The 1979 "A Song For Europe" final was never held at all, due to a strike by BBC sound engineers. The juries had to judge using audio recordings of the rehearsals. The songs were presented to the public on Terry Wogan's radio show the following day, after the result was known, followed later in the day with a spot on the TV magazine show "Nationwide", where the top 5 were revealed and the winners, Black Lace, were interviewed as guests on the show. As a result of this industrial action, all future contests were staged at BBC studios and not as outside broadcasts from venues. The 1980 result ended in a tie between Prima Donna's "Love Enough For Two" and Maggie Moone's "Happy Everything". To resolve this, in an unrehearsed panic, host Terry Wogan called back the juries to announce their favourite of the two songs. This led to extreme confusion when the scoreboard failed to keep up and some juries contradicted the results they had given earlier. Prima Donna won, with eight juries to Maggie Moone's six. A detailed check of the votes after the show did confirm that Prima Donna were the correct winners. Prima Donna were the first winners of the competition specifically formed to take part in Eurovision. This became the norm in the 1980s and the artists taking part in the contest became more and more obscure and amateurish. However, a few notable acts did enter the contest in the 1980s, with scant success. Liquid Gold, Alvin Stardust, Sinitta and Hazell Dean all failed to come through the heats.
