Sergio Blanco Rivas and Estíbaliz Uranga Améraza were both former members of Mocedades, the group which represented Spain at the 1973 Contest with "Eres tú", Estíbaliz is in fact the sister of lead singer Amaya Uranga, and both "Eres tú" and "Tu volverás" were written by prolific Spanish composer and lyricist Juan Carlos Calderón. Sergio and Estíbaliz also recorded an English language version of their entry, then entitled "Love Come Home".
The song was performed seventeenth on the night, following Portugal's Duarte Mendes with "Madrugada" and preceding Sweden's Lasse Berghagen with "Jennie, Jennie". At the close of voting, it had received 53 points, placing 10th in a field of 19.
It was succeeded as Spanish representative at the 1976 contest by Braulio with "Sobran las palabras".
