Stephen Sondheim's song, Send In the Clowns, from the musical 'A Little Night Music' was written late in rehearsals for the actress Glynnis Johns, playing the part of Desiree. A song of regret and anger, the part has famously been played by Judi Dench, and the song became an independent hit, sung by Judy Collins, Shirley Bassey and Barbra Striesand. Hannah Waddingham played the youngest ever Desiree in Trevor Nunn's production, and used her memories of an unhappy relationship to inspire her performance.
