The format of the show and the manner in which the winner is chosen has gone through many mutations. In its early days, there was a round of televised semi-finals, with the winner chosen by regional juries situated across the country. This format was used until 1960. During this era the show was known as the "Festival of British Popular Songs" (1957) and "Eurovision Song Contest British Finals" (1959 and 1960). In 1961 the show became known by its more familiar title, "A Song For Europe", with regional juries once more deciding the winner. Typically, during that period, singers would be invited by the BBC to choose and perform a song that they liked from the shortlist 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.
