I've completed the Saturday Christmas Crossword and today's Herculis and I am happy that I have matched up three of the shaded clues i.e. Turtle Doves, French Hens and Gold Rings and the fourth is either Pear Tree Partridge or Partridge Pear Tree. Question is which one is the more appropriate because according to the song Partridge (in a) Pear Tree but I've also seen it written Pear Tree Partridge. Help!
