The Fox Head costume was worn by Peter during the tour for the Foxtrot album in 1972/73.
In 2012 Peter told Uncut Magazine:
“… on Foxtrot I wore the fox head and the red dress. My wife, Jill, had a red Ossie Clark dress which I could just about get into, and we had a fox head made. The first time we tried it was in a former boxing ring in Dublin, and there was just a shocked silence. [Laughs] You could feel the horror. I thought, ‘Oh, this is exciting!’”
