Proceeds from the event will help maintain Ivy House, Pavlova's former home, and a donation will be made to the bursary fund at RBS. Both very worthwhile causes in my opinion. I've heard cast and performance details will be published as soon as is possible but it will no doubt be a fantastic evening!
The event is part of Pavlova2012, a week of events in June at Ivy House (as well as around London in the summer) to celebrate Anna P making it her home in 1912. Details of the events are here:
