There were several all-girl bands in the 1960s named The Ladybirds, some of them who performed fully-clothed and some who did not.
Like the Monkees, eventually they learned how to play their own instruments.
The line-up seen here includes Robin Sherwood lead guitar, vocals , Barbara Branch guitar, vocals , Marcelle Mitchell bass , Rosita Quintana drums and Deborah Dayan organ.
The Ladybirds was apparently quite the popular name for female pop groups in the 1960s.
