An initial candidate troupe was the existing BBC TV Beat Girls, but an ex-dancer from the Beat Girls, Jo Cook, was eventually engaged to create a troupe, the all-female Go-Jos, with Cook as choreographer. The Go-Jos also worked outside of "Top of the Pops", notably for two years on the Val Doonican show – Doonican said in 1968 "I thought the Gojos were fabulous, something really new. When I got my own television series I just had to have them with me."
