July 29th 1968 the top-less all-girl band played in “Stjernesalen” in Bergen, and “Dagbladet”, a major newspaper, ran on July 30th, articles on their top-less act both on page 1 and 2. They gave a short show and played numbers by The Hollies and the Supremes. Their booking agent was Pierre Beauvais in Copenhagen, Denmark.
In September the same year they shared the stage with The New Yardbirds at Fjordvilla Rock Paramount in Roskilde (Later called just The Roskilde Festival). The New Yardbirds changed their name to Led Zeppelin later that year.
