La Paloma is a beautiful Spanish song.

That song came out in the 1970s. It was also sung by various singers in German.

If you want a good rendition of pop songs of the 1970s and '80 sung in Spanish (or French or German), get a CD of Nana Mouskoui. There were lots of pop hits sung in various languages aside from the original language in the 1970s and '80, or the 1960s.

Remember, "Never on a Sunday" Different linguistic versions of that famous song were done.

Una plaoma blanca was a huge hit in Britain in the mid 70's by the singer and record producer Johnathan King.

"La Paloma" is a popular Spanish song that has been produced and reinterpreted in diverse cultures, settings, arrangements, and recordings over the last 140 years. The song was composed and written by the Spanish composer from the Basque region Sebastián Iradier (later Yradier) in the 1850s. In 1859 it was registered at the copyright office in Madrid as a "Cancion Americana con acompañamiento de Piano".[1] Iradier was to die in obscurity within few years, never to learn how popular his song would become.
