9 Sounds right. Each queen has a solo, plus the opening/closing numbers and "House of Holbein" - that makes 9. There's also a megamix included in the 70 minute run time - so you're actually getting about 65 minutes of new material.
The show is a fun, high energy concert dependent wholly on the vocal gymnastics of the cast. The book is, in some places, cringeworthingly bad. A series of "jokes" centered around the one or two character traits we learn about each woman - so prepare for a lot of "I DIED IN CHILDBIRTH" or "I LOST ME HEAD MATE!" jokes.
That all being said... I've seen it twice. |
