One thing that The Zoo libretto in the Archive lacks is a reference to a soprano solo that the heroine was supposed to have upon her entrance. According to those who have put on The Zoo, a tune appears in the score, but no words. S-A Cole has heard one sung twice (at the West Chester/Basingstoke conference of 1989, and at the Chicago G&S Society's production).

The number can now be seen to be entirely regular in shape and in the form of two similar verses.

The paper-bound score costs £7.50, and the cloth-bound one is £25.00. You might want to contact the publisher for a US$ quotation.
