I second KirbyCats's question. I doubt that the producers would close a show that continues to make money, especially in this economy but it would be interesting to see a musical as well as its sequel playing at the same time.
I never realized how many broadway shows had sequels. Actually, I never even considered the idea of a broadway sequel until hearing about the Phantom sequel. This whole thread kind of killed me a little bit on the inside. I can see it now though: Ave Q2: Return of the Puppets starring Paris Hilton as Lucy and Kevin Federline as Nicky...
