The Eurovision Song Contest 1974 was the 19th edition of the annual Eurovision Song Contest.
It was held in the seaside resort of Brighton on the south coast of the United Kingdom. The BBC agreed to stage the event after Luxembourg, having won in both 1972 and 1973, declined on the grounds of expense to host the contest for a second consecutive year.
The winner of the Contest was Sweden with the song "Waterloo" which was performed by the band ABBA, that went on to become one of the most popular recording acts of all time. ABBA are among the few Eurovision winners to achieve international superstar status. Sweden's win was their first. Katie Boyle returned to host her fourth Eurovision Song Contest (after hosting the contest in 1960, 1963 and 1968).
