The surgeon general has a warning on cigarette packs for smokers. Is "Bye Bye Liver," the title of this sketch comedy revue, a warning for would-be drinkers? The show, which may be better with liquor, has been knocking them back in Chicago and Milwaukee. Now it has opened in the Twin Cities under the auspices of Actors Theater of Minnesota with talent drawn from the likes of Brave New Workshop Comedy Theater and Stevie Ray's Comedy Cabaret. Cast members include Laura Mahler, Adam Qualls and Mike Rylander under director John Haynes. Cheers?
