'20s & '30s Swing in NYC June 21st?

I’ve been asked by the redoubtable Rich Conaty of The Big Broadcast to this event:

at Hunter College, Kaye Playhouse, East 68th Street between Park & Lexington Avenues. I haven’t really made up my mind: I have classes that night, so I do have to be in the city late anyway . . . Anyone else interested?
