Det rör sig kring Svante = There are things going on with Svante

Frida was one of the singers who took part in this music show.

Svante, as mentioned in the title, was Svante Thuresson, a well-known Swedish jazz singer (the only male in the above picture). Anna Sundqvist (dressed in white in picture) and Lena Hansson (dressed in black) took part in this show as well.

The show was produced by Monica Eek.

** There is some doubt to the date, time and channel of this entry. There is no reference in TV guides.

Any idea what songs she performed?
