The group skyrocketed to fame when they represented Spain in the 1973 Eurovision Song Festival with the song "Eres tu" composed for them by J.C. Calderon. They finished in second place but the following year the song became a world hit and one of the very few Spanish language songs to reach the top 10 on the Billboard Hot 100 chart in March 1974. Other famous songs by Mocedades include "Tomame o dejame", "El vendedor", "La Otra Espana" and "Me siento seguro", but none of them reached the heights of "Eres tu" which, to this day, remains a favorite in airplay lists of Easy Listening radio stations in the USA and has been featured in many films. In 1980 Mocedades signed up with CBS Records (now Sony) and as of 2013 24 different people have been part of the group, yet no formation has been able to repeat the success of the first historic line-up.
