The 1967 graduating class of Inglewood, California’s Morningside High School voted Vicki Lawrence “Most Likely to Succeed,” but they couldn’t possibly have guessed the form this success would take. After Lawrence sent San Antonio-born comedian Carol Burnett a local newspaper article pointing out the resemblance between the two women, Lawrence was cast to play Burnett’s younger sister on the now-classic Carol Burnett Show, which she did for years, but Lawrence most famously played Burnett’s mother in a series of sketches that was later adapted into the TV show Mama’s Family. That’s of course leaving out the part in 1972 when Lawrence topped the music charts with “The Night the Lights Went Out in Georgia,” a musical murder mystery penned by her then-husband Bobby Russell. Considering the career she’s had, a solo “two-woman” show makes about as much sense as anything else, but Lawrence, in a press release, cautions: “My show is not a retrospective. It is a mixture of stand-up comedy, music and my observations about real life ... new material with a more modern and cutting edge.” She also says to “expect the unexpected” but the seniors at Morningside High could’ve told you that. $24.50-$49.50, 7pm Sun, Aug. 21, Tobin Center for the Performing Arts, 100 Auditorium Circle, (210) 223- 8624, tobincenter.org.
