La golondrina (English: "The Swallow") is a song written in 1862 by Mexican physician Narciso Serradell Sevilla (1843–1910), who at the time was exiled to France due to the French intervention in Mexico.
The lyrics come from a poem written in Arabic by the last Abencerrages king of Granada, Aben Humeya, in a translation by Niceto de Zamacois, which Serradell found in a magazine used as packing material.
Other notable cover versions are by: Solomon King recorded the song in 1968 and it became an instant international hit.
The song, recorded by 13-year-old Heintje, became a German number-one hit in August 1968 (title: Du sollst nicht weinen, "Thou shalt not cry").
Hegerland's songs have been released on nearly 30 million albums worldwide, most of which are with Roy Black and Mike Oldfield.
