Mystic Players Revival resumes theme nights for their  latest impromptu revue at the library, with this month’s edition titled “Comedy Tonight.” Bring a comedic monologue, scene, song, poem or whatever with you to perform — or just sit back and relax in the audience. Mystic Players Revival is a nonprofit organization created by a group of Medford residents who are bringing back a community theatre experience to the city similar to the Mystic Players, who performed from the early 1970s until the early 2000s. The group presented their first formal performance, “The Mystic Cabaret,” this past February. More public performances are being planned. Questions? Email mysticplayersrevival@gmail.com.
