The all girl, vocal only group, were a rarity in Australia's "mod" music scene of the 1960s, dominated as it was by all male rock bands and solo artists.
Within 12 months they had become widely known for Marcie's powerful voice and the Cookies superb vocal harmonies and their synchronised stage movements as a result of their appearances on national TV shows, particularly on the pop music The Go!!
With Peter Williams, they went on to form a new group called Spirit of Progress who recorded a couple of singles on the Philips label and were the support act also for Cliff Richard on tour.
In their 40-year career they have toured with The Monkees, Gene Pitney, Cliff Richard, The Shadows, Roy Orbison, Tom Jones, Del Shannon, Ray Stevens and other performers.
In mid-2008, Marcie became a presenter on 100.7 Highlands FM, a community radio station based in the Macedon Ranges in Victoria, Australia, where she co-hosts a weekly show entitled "Blonde and Blonder".
