available. Household names such as Petula Clark, Lita Roza, Anne Shelton, Frank Ifield, Ronnie Hilton and David Hughes were amongst the contenders for the UK competition, none of whom were able to secure the much cherished ticket to the Eurovision final. In the early 1960s, record companies became involved in the selection process for the first time and submitted songs by their artists. This produced hits for Craig Douglas, Karl Denver, Jackie Lee, Kenny Lynch, Vince Hill and Ricky Valance, but again, none of them were selected to go forward to the Eurovision Song Contest final itself. From 1964 up until 1975, an artist would be chosen by the BBC, and that artist would sing all six songs (five in 1966 and 1967) in the selection, and the public (bar 1964 and 1971) would choose by postcard which song they would like to represent them in the contest. Regional juries selected the winner in 1964. A postal strike in 1971 prevented the ballot from taking place, so regional juries were once again constructed to pick the winner. In 1972, national power cuts meant that the broadcast of the show was blacked out in many areas, leading to a much lower postal vote. In its early days of this format, only "light entertainment" singers were used, such as Kenneth McKellar and Kathy Kirby. However, the poor showing of McKellar in Luxembourg (he placed 9th of 18 entries with scores from only 2 countries, including top marks from Ireland) prompted the BBC to use more mainstream pop stars, which led to a run of successful results for the UK. This idea was dropped due to the low number of postal votes cast in the contest of 1975, in which all six songs were performed by The Shadows, and after objections from songwriters who felt The Shadows, and the BBC's selections in general, were not the sort of artists they wanted to represent their music. After 1964, the "Song For Europe" selection process was incorporated into other BBC light entertainment shows, in addition to the songs being broadcast on BBC Radio programmes. Typically, the performer would sing one song a week either on their own series or as a guest on another regular BBC TV show, more often than not, televised on Saturdays. This culminated with the performer singing all the songs one after another in a special edition of the given show.
