Joseph & the Amazing Technicolor Dreamcoat, through May 10. You gotta love a show that rhymes "fratricide" with "take them all for a ride." Beyond the catchy lyrics, director Marc Robin instills Andrew Lloyd Webber's chestnut with fresh humor and hilariously ingenious original touches. If you aren't smiling by the end, something's amiss. CS
Mariette In Ecstasy, Lifeline Theatre, through April 5. Even if your notions of Catholic clergy are limited to The Thorn Birds and Nunsense, Lifeline's look at girl-group psychology in a cloistered community raises issues relevant to sacred and secular societies alike. MSB
The Robber Bridegroom, Griffin Theatre, through March 29. Eudora Welty gave this classic European fairy tale a pre-Civil War South spin—conveyed in this spritely, pleasing, cartoon-like musical version—reminding us of the duality of male and female alike. JA
Xanadu, Drury Lane Theatre Water Tower Place; through March 29. It may be based upon the one of the worst movie musicals ever made, but this adaptation truly is high-camp heaven on roller skates. SCM
