The song is the German version of the track "A Star Looks Down Tonight", which appeared on the original release and was included on the CD single.
Due to its popularity, Gwen also decided to include "A Star Looks Down Tonight" as the closing track from her second studio album, Ganz Schön Frech (1994).
A French-language version, titled "Au ciel, une etoile" (featuring French singer Nadège) was also released as a single in late 1994.
Hasselhoff and Gwen performed "Wir zwei allein" live on several German TV shows, including Verstehen sie Spaß.
With "Wir zwei allein", Gwen also achieved international recognition, becoming her first top-ten single in Austria, Germany and Switzerland.
