From The Guardian...
When 15 million viewers tuned into Top of the Pops each week during the show's 1970s heyday, the appeal extended beyond the hitmakers on the screen to those who were not appearing, since an absent act's single was interpreted by the show's all-female dance troupe, Pan's People. Their silky routines were choreographed by one of their dancers, Flick Colby, who has died aged 65 of bronchial pneumonia, after suffering from cancer.
Colby, an American with long blonde hair and a megawatt smile, confected slinky, semi-risque and often extravagant Top of the Pops routines for Pan's People for eight years. She continued to work on the show with subsequent troupes, choreographing moves to suit a range of musical styles such as glam rock, folk, soul, disco and punk.
