This was the clearest topless pic of Lesley and also featured the only known nudity from future West End superstar Elaine Paige. She made this obscure TV film the same year she burst into stardom as Eva Peron in Evita.
Finally, the show featured the only film appearance from the late, great American president, George Washington. It’s surprising to see him in a British film, since the Englishmen of his century took a rather dimmer view of his actions than their American counterparts. I guess that the passage of two centuries mellowed them out a bit. The father of his country was a few hundred years old at the time, and looked every bit of it.
