Good karaoke bars need several things: cheap booze, a thick songbook, a DJ capable of inflating your ego, a no-cuts-no-butts-no-coconuts method of choosing singers and, perhaps most important, a loyal following of wannabe Axl Roses who will sing along to the lyrics of almost anything and cheer you on while you do the Vanilla Ice dance during instrumental breaks. Charlie Brown's has all this and more. The cheap booze flows from morning until night, and you can keep your pipes primed during the five-times-a-week piano sing-along. That way, when the karaoke starts at 9:30 p.m. on Sundays, you'll be ready to join in with the rest of the appreciative audience, encouraging every intoxicated rendition of "Ice Ice Baby." Word to your mother.
