Partying Is Such Sweet Sorrow

Public Theater gala performance of Romeo & Juliet. Delacorte Theater, nr. Central Park W. and 81st St., 6 p.m. Expected guests at tonight’s show (which stars Oscar Isaac and Lauren Ambrose) include Tony Kushner, Mike Nichols, Eric Bogosian, and a bajillion famous actors. In other words, the Romeo & Juliet cast are performing what may be the most famous roles in Western history to a private audience of the world’s most accomplished theater professionals. It's like distributing loaves and fishes to Jesus.

Sundance Channel Live From Abbey Road launch party. Daryl Roth Theatre 20 Union Square E., nr. 15th St., 7:30 p.m. Ben Harper and the Innocent Criminals will perform for attendees including Laura Dern, Jamie-Lynn Sigler, and numerous socialites. Did the theatrical establishment scheme behind Laura Dern's and Jamie-Lynn Sigler's backs to give them the impression that the Romeo & Juliet gala was actually tomorrow night? Not cool, theatrical establishment!
