Meow Meow, the Hush, Grape Drink, Food Hole, Solid State... the list of defunct all-ages clubs in Portland is startling, especially when compared to the longevity of their boozy brethren, the bar venue. Age-restricted clubs seldom close up shop, but few ventures are more doomed to fail in this town than the all-ages showspace. With their cozy confines and mustachioed logo, the Parlour has been struggling to keep their head above water as of late and will shut down by the end of this month unless they raise some much-needed capital. Tonight's "Save the Moustache" benefit show intends to do just that, which will hopefully assist the Parlour in avoiding a fate that has claimed so many previous all-ages spaces in town.
