Somebody messed up somewhere. Because People Matter, Sacramento’s progressive humanist rag, is having a fund-raising concert to support their journalistic efforts and, in some bizarre booking snafu, they’ve employed George Shrub to provide the entertainment. George Shrub, the world’s only singing CIA agent, whose ties to the Committee to Intervene Anywhere date back to the Cold War Days. Shrub, author of songs like “Sing a Song of Sweatshops.” Shrub, whose music reinforces the idea that “the business of America is none of your business, that unions are never civil and that the proper place for himself, like Wal-Mart, is everywhere.” His folk songs hardly seem in step with the kind of liberal thinking found in Because People Matter. Still, maybe the folks at BPM are hoping the hilarious songwriting satirist Dave Lippman, rumored to be touring with Shrub, will make an appearance. Find out at 7pm on Sunday. Admission is on a sliding scale from $5-$500. Sierra 2 Theater, 2791 24th St. Call 444-3202 or visit www.davelippman.com for more information.
