Eres tú

It is one of the few musical acts from Spain to have scored a top ten hit in the United States, being the only one sung entirely in Spanish.

TVE filmed a video clip with the group singing the song in a studio that was distributed to the other participant broadcasters as established by the contest regulations.

[2] On 7 April 1973, the Eurovision Song Contest was held at Grand Théâtre in Luxembourg hosted by the Compagnie Luxembourgeoise de Télédiffusion (CLT), and broadcast live throughout the continent.

"Eres tú" was succeeded as Spanish representative at the 1974 contest by "Canta y sé feliz" by Peret.

One of the biggest scandals at Eurovision resulted from the perceived similarity between the melody of "Eres tú" and that of Yugoslavia's 1966 entry "Brez besed".

However, the authors of "Brez besed" neither officially complained nor filed a lawsuit, as neither was common practise at the time.

[citation needed] There were also several covers of the song in both English and Spanish, only one of which –"Touch the Wind" by Eydie Gorme–, charted, becoming a minor Adult Contemporary hit.

[10] The song was featured with footage of Mocedades' Eurovision performance with Amaya Uranga, Carlos Zubiaga, and José Ipiña appearing live on stage towards the end.
