Bad songs covered badly can be amusing--and Romuva Productions' cabaret-theater piece, which includes such gems as "Physical" and "A Whiter Shade of Pale," certainly has that going for it. Len Jenkin's script is a mishmash of hallucinatory images that range from dull to disturbing as Spin and Marlene Milton, a divorced couple, do their thing in small bars off isolated highways; the brightest part of their tired, lonely existence is their Vegas-style spangled costumery (by Jana Stauffer). But they still try to spread a New Age/Zen message of love and being present in one's life by telling stories about alien abductions and horrible car accidents. Audre Budrys and Kestutis Nakas nail their characters, but they struggle to rise above material that's neither enlightening nor funny. If only there were more songs and less patter. Through 11/27: Sat 10:30 PM. Davenport's Piano Bar & Cabaret, 1383 N. Milwaukee, 773-278-1830. $10; 2 dr. min.; 21+.
