In the city for the weekend? Here are some things to do:
The original high school musical Bye Bye Birdie flies at the North Shore Music Theatre. Thomas Garvey has a review here.
Assassins, Stephen Sondheim's musical mashup of our country's dark underside plays at the Boston Center for the Arts. Company One is also presenting a late night show: John Kuntz and Rick Park in After School Special.
The Factory Theatre presents Maria Ines Fornes's play Mud. Forne's work is a very strong influence on contemporary drama and it is always interesting. But it is rarely done outside of the conservatory settings.

The Publick Theatre is running Noel Coward's Hay Fever, (the Publick is now in full rep mode with Hay Fever and The Seagull running till September, so check the website to see the dates.)

The F.U.D.G.E. Theatre Company presents a musical about a co-ed Catholic Boarding school. It's titled Bare and plays at the Arsenal Center for the Arts.
Gloucester Stage's Going to Saint Ives closes this weekend.
