In Efter endnu en dag the bombastic rock of Stakkels Jim and Gas 5 was replaced by a more eclectic sound, making this album their equivalent of Sgt.

[citation needed] "Pilli villi" and "Pas på svinget i solrød" are up-tempo rock songs, while "De fem årstider" and "This Is My Life" are ballads.

[1] From this album "Sirenesangen" / "De gule enker" and "Pas på svinget i solrød" / "Bella Donna" were released as singles.

Efter endnu en dag was released on CD in 1987 with Gas 5 but due to lack of space, "Mama Cucu", "Twilight Birds", and "Stenalderjazz" were omitted.

Efter endnu en dag was released in Spain as Al cerrarse un nuevo dia with song titles in Spanish translation, but sung in Danish.
