The Spanish vocal group, Mocedades (Youths in Spanish) scored a top 10 hit with "Eres Tu", which translates to "You Are", in 1974. It was released as a single, I assume, at the end of 1973. The B-side was an English translation of the same song, under the title, "Touch The Wind". American artists, such as Eydie Gorme, Perry Como, and Johnny Rodriguez, have covered "Eres Tu", and in Gorme's case, "Touch The Wind", as well.
I remember hearing "Eres Tu" on the radio back in the day. Now, we all get to see the faces of the band.
