Finally, TVE accepted songs from seven composers, among which "Yo soy aquél" sent by Manuel Alejandro and sung by Raphael was internally selected as its entrant in the contest.
[2][3][4] On 5 March 1966, the Eurovision Song Contest was held at Villa Louvigny in Luxembourg hosted by the Compagnie Luxembourgeoise de Télédiffusion (CLT), and broadcast live throughout the continent.
[5] Manuel Fraga himself, the Minister of Information and Tourism, on whom TVE depended at that time, had to obtain special permission so that Raphael could leave the garrison for a few days to travel to Luxembourg.
[6] He performed "Yo soy aquél" eleventh on the evening, following Sweden's "Nygammal vals" by Lill Lindfors and Svante Thuresson and preceding Switzerland's "Ne vois-tu pas?"
Raphael also recorded a French language version of the song, with lyrics by Don Diego, with the title "Dis-moi lequel" that was released in France in a vinyl single by Disques Vogue under license from Hispavox.
