pennsicdance: Two dance classes at 5pm, Thur.8/12?

[Krege, Barbara B]

There appears to be two dance classes for the dance tent at 5pm, on Thursday 8/12.  
Since I am singing in the known world choir that performs at 6pm Thursday, I hope the Dance Review class for that night's dance revel will be moved to 4pm.
 
Thanks, Jayne Barber, Outlands
