Every year the Folkpark arrangers met artistes and managers to book upcoming tours at a Folkparksforum.  The one for the following Summer 1967 featured a report about The Hep Stars and their success throughout 1966.

The Hep Stars were interviewed in this report about them performing more than 170 folkpark shows between 29 April and 2 September 1966 (this was the number of shows at the time of the report, it could be there were more after 2 September 1966).
