Back when former City Attorney Tom Carr was attempting to shut down the Blue Moon for, among other alleged infractions, rampant on-premises pot dealing and inhalation, the legendary tavern had to play down its herb-friendly image. Now, as the Moon celebrates its 77th birthday with a week’s worth of commemorative events, Seattle has a mayor and city attorney who support full pot legalization. So we’ll come right out and say it: Back when the tavern hosted regular Grateful Dead Sunday nights in the ’80s and ’90s, you could get a contact high simply by walking through the rickety front door. But the real draw then, as it will be during this one-night-only revival, is the music. Some hippie will spin a series of righteous Dead bootlegs, preceded by a six o’clock set from the Dead-on cover band Kuli Loach. We’re not saying there’ll be tons of ganja consumed, but we’re pretty sure no one will get cuffed if there is. MIKE SEELY
