Though there are no reported renderings of the Cheers theme song at this weekly Wednesday night warblefest, the atmosphere at Llywelyn's upstairs-bar karaoke is one in which everybody knows your name -- even if the regulars are so consistently tipsy, it's a wonder anybody remembers it. More than just an outlet for sloshed sorority girls or a showcase for American Idol wannabes, the karaoke here -- which lasts from about 10 p.m. until closing and yet often serves as the social-calendar high point for many a Wash. U. grad student, St. Louis theater scenester and off-duty Post-Dispatch reporter -- is about being and becoming friends. Social cliques bleed happily into one another, bonds are fast forged over off-key covers, bartender Amy is lusted over by men and women alike and nobody seems to leave without hooking up in the bathroom at least once. Debates about whether karaoke is cool (or distinctly uncool, or only cool when approached from a detached, ironic worldview) prove irrelevant here. At Llywelyn's, karaoke is love.
