Bailegangaire, Irish Repertory at Victory Gardens, through Feb. 15. The great Irish oral tradition springs vividly to life in this quasi-ghost play of stunningly rich language, supremely well acted. Mary Ann Thebus is indelible as the ancient story-teller. (Abarbanel)

The Elephant Man, The Side Studio, through Feb. 15. Bernard Pomerance’s sensitive and engaging script, set in Victorian London and based on the life of the horribly disfigured John Merrick, is given a simple, yet deeply textured outing by the Side Project. (Reed)

My Own Stranger, Writers’ Theatre, through March 28. Adapted from the letters and poetry of Anne Sexton, this production is a haunting collage of a fragile life with bravura performances by Marilyn Campbell, Mary Beth Fisher, and Kymberly Mellen. (Reed)

San Valentino And The Melancholy Kid, House Prod., through March 6. The folks who gave us Death And Harry Houdini now goes Wilder West: cattle stampedes, bounty hunters, shootouts, dance-hall girls, and a full-out rock-and-roll band. Yee-ha! (Barnidge)
