Plans for tonight: Post-holiday cheer
• Octapella, the eight-man a capella singing group, plays the first of two shows tonight at the Rose Wagner Performing Arts Center, 138 w. 300 South, Salt Lake City. Show starts at 7:30. (A second show is Tuesday, same time, same place.) Tickets are $14, at ArtTix.
• It's the last night of Off Broadway Theatre's holiday spoof, "The Grouch Who Stole Christmas," at the OBT, 272 S. Main, Salt Lake City. Show starts at 7:30. The show is sold out, but there is a standby line.
