On the ninth day of Christmas the ladies Anne, Bella, Cary, Debbie, Eileen, Fran, Gill, Honor and Iris entered a dancing competition. In some order they had labels ‘One’, ‘Two’, ‘Three’, ‘Four’, ‘Five’, ‘Six’, ‘Seven’, ‘Eight’ and ‘Nine’ on their backs. They each danced a different dance chosen from cha-cha, charleston, foxtrot, jive, polka, quickstep, samba, twist and waltz.
For any lady’s name and label there was just one letter of the alphabet that occurred (once or more) in both. The same was true for any lady’s name and their dance, and also for any lady’s label and dance.
In alphabetical order of their names, what are the numbers of the nine ladies?
