This production has been a great success (more than I think any of us would have imagined) and IMO is a great theatre experience, though it pretty much has killed any chance of Broadway revival for the next 5-10 years I imagine. Is there a closing notice? I wonder if it'll be the longest running production of Sweeney Todd in New York, ever. If not #1, it'll certainly be (and already is) #2.
Give me claws and a hunch, just away from this bunch.
