After the war Hudson designed costumes and scenery for Sadler's Wells and Ballet Rambert. This interest in ballet led Hudson to meet Nesta Brooking, who had opened a ballet school in Primrose Hill. Hudson became the Brooking School of Ballet's artistic director. As well as colleagues, the two became lifelong companions, and shared their lives until Brooking's death in 2006, aged 99. With the musical director Norman Higgins, Hudson and Brookings worked on projects with Cecchetti scholars and with the BBC as well as producing Brooking's own shows.
