According to a mid-August 1967 TV report, The Hep Stars were due to take part in Önskeprogrammet on 4 September 1967. This must have been the filming date, since there was no Önskeprogrammet broadcast on that date.
There was an Önskeprogrammet broadcast on 10 September, hosted by Per Grundén. It's unclear if this was the broadcast The Hep Stars were in.
More clarification needed.
