"Yes, but which Harry Kipper?" one might well ask. Both of the Kipper Kids, whose bizarre conceptual comedy positioned them as sort of the Laurel and Hardy of the avant-garde in the 1970s and '80s, used the name Harry. The team consisted of Martin von Haselberg (an Argentinean of German descent who subsequently married Bette Midler) and Brian Routh, an Englishman descended from a family of music-hall entertainers and street buskers. It's Routh who is here this weekend to make a keenly anticipated one-night stand (it's first come, first served general admission, boys and girls, and doors open at 8). Having emerged in the 1980s as an individual presence (sometimes teaming up with Karen Finley--they appeared in Chicago as "Mr. and Mrs. Mouth" in 1983), Routh has been working solo more frequently of late. He describes his current untitled piece as "a vocal rant and rave using musical instruments, dolls, found objects, many books, and my baggy British body." Expect his manic meditation on the volatility and fragility of human nature to be rude and ridiculous, astral and anal, uneven and invigorating, infantile and illuminating. At Club Lower Links, February 2 (954 W. Newport, 248-5238). Saturday, 9 PM. $8.
