Ronald Colman playing the banjo.
An instrument he learnt when he joined the Bancroft Amateur Dramatic Society, where he “…acted Wilde, sang the English drinking songs, learned Gilbert and Sullivan and how to play the banjo.”
The last picture is from the set of The Magic Flame, where “…he played a circus clown and a villainous count. He introduced the idea of the clown playing a banjo, being an old virtuoso from his amateur theatrical days, and serenaded the astonished company with his repertoire.”
