María de los Ángeles Felisa Santamaría Espinosa, professionally known as Massiel, is a Spanish pop and protest singer, actress, and songwriter. She won the Eurovision Song Contest 1968 with the song "La, la, la", being the first performer from Spain to ever win the contest.

The Eurovision Song Contest 1968 was the 13th edition of the annual Eurovision Song Contest. It took place in London, United Kingdom, following the country's first victory at the 1967 contest with the song "Puppet on a String" by Sandie Shaw. Despite having won for the first time the year before, it was actually the third time that the United Kingdom had hosted the competition, having previously done so in 1960 and 1963, both of which also took place in London. Organised by the European Broadcasting Union (EBU) and host broadcaster British Broadcasting Corporation (BBC), the contest was held at Royal Albert Hall on 6 April 1968, and was hosted by Katie Boyle for the third time. It was notably also the first time that the contest was broadcast in colour.
