From 1968 to 1975, these performances were then immediately repeated before viewers were asked to cast their votes by mail. The following week, the winning song would be announced and performed once more, although there was a two-week wait in 1965. In 1968, Cliff Richard performed the songs only in a special edition of Cilla Black's eponymous TV series (broadcast on Tuesdays), without having sung them weekly beforehand. The various shows chosen for the "Song For Europe" performances were The Kathy Kirby Show (1965 shown on Fridays), Kenneth McKellar's A Song For Everyone (1966 shown on Thursdays), The Rolf Harris Show (1967), Cilla (1968 and 1973), Lulu (1969 and 1975), It's Cliff Richard! (1970, 1971 and 1972) and Clunk, Click... As It Happens (1974) – when in a break with the format, Olivia Newton-John performed three songs a week for two weeks rather than one a week for six weeks. Originally, Cilla Black's 1974 nine-part BBC series was also scheduled to feature the 'Song for Europe' process, but Black was uncomfortable at promoting another female singer (Newton-John) each week throughout the series' run and in a rather last minute decision, the BBC arranged to move the process to another show, necessitating the contracted process. This period was highly successful for the UK in the Eurovision Song Contest. Author and historian John Kennedy O'Connor notes in his book The Eurovision Song Contest – The Official History, that every UK entry to the contest from 1967 to 1977 finished in the top four, with only three songs not being first or second. Indeed, the UK were only 7 points short of four consecutive victories from 1967 to 1970. 1970s and 1980s In 1976, the method used from 1961 – 1963 was reinstated. Twelve songs were performed by artists chosen by the songwriters themselves and the winner was chosen by regional juries across the country during a stand-alone show called "A Song For Europe". This system produced an immediate success by choosing the song which went on to be the Eurovision winner that year, "Save Your Kisses for Me" by Brotherhood of Man. The first few years of the revamped format also saw a plethora of well-known names take part in the competition.
