Vårvise
"Vårvise" (in English: "Springsong") is a duet-single, from Danish singer Sebastian and Norwegian singer Sissel Kyrkjebø in 1987.
It is written by Sebastian and released as vinyl single taken from the Danish version of Sissel's debut album Sissel (1987). They performed it together on the Danish TV-show Under Uret, hosted by Hans Otto Bisgaard. That also was Sissel's debut on Danish television, and this song made her a familiar name in Denmark.
The B-side was " Summertime", which Sissel also performed on Under Uret.
