The Turtle Creek Chorale presents Songs We Can’t Sing on Stage, a one-night-only, adults-only cabaret performance on Saturday, May 2 at Oak Cliff Assembly (919 Morell Ave). Featuring host Helen Holy and special guest Denise Lee, this irreverent evening highlights edgy, humorous, and unexpected musical selections that push beyond the boundaries of a traditional chorus concert. Performances take place at 5 p.m. and 8 p.m., with tickets starting at $40 at TurtleCreekChorale.com. Audience members should note the show includes explicit language, partial nudity, and mature themes.
