"Känner Du Fia Jansson?'" (Do you know Fia Jansson?), the lyrics was originally written for the show Den förgyllda lergöken, by Emil Norlander in 1900. The music was based on the spanish ballet Cachucha from 1836. In 1944 a movie was made based on the show called Fia Jansson från Söder. Hansson sings the song when he introduces his old friend, the hippopotamus Fia Jansson. Only the first verse of the song are used.
