Some pretty funny comedians are coming to Bumbershoot this year and some of them are putting on a pre-event comedy show Friday night at Lo-Ball (2220 NW Market, lower level). Sadly, we don’t know which comedians will be there. (They have non-compete clauses in their contracts that prevent them to advertise the show.) But we’re told some national acts will stop by Lo-Ball and perform an all-ages show in the intimate confines of the Live Girls! Theater. Doors open at 10:30 p.m. and there is a $5 cover.
