I'm not saying I don't believe it and I'm not saying that I don't think it's a possibility that the team behind WEST SIDE STORY would be willing to buy out Olivo's contract with IN THE HEIGHTS, but they'd at least have to allow for a substantial amount of time (two weeks, even) before she could actually leave the show.
Her getting cast on a Thursday and leaving IN THE HEIGHTS a few days later gives the show no time to cast a replacement for her, short of bumping up an understudy temporarily and working like crazy to get someone fast.
I think Karen is a brilliant talent and would be happy to hear she has this opportunity (as unlikely a choice for Anita as she may be,) but a couple facets of the circumstances surrounding her supposed casting just seem shady to me, including the fact that I was told last week by a member of the production team behind a different show that Olivo was in negotiations to be cast in that particular project.
Tonya Pinkins: Then we had a "Lot's Wife" last June that was my personal favorite. I'm still trying to get them to let me sing it at some performance where we get to sing an excerpt that's gone.
Tony Kushner: You can sing it at my funeral.
