It’s no secret that Bruce Springsteen is playing Portland on March 28 and Seattle on March 29. Lesser known is the recently announced news that another troubadour with the initials BS, Bob Schneider, will be hitting those cities one day after the Boss; he has gigs at the Doug Fir in Portland on March 29 and Chop Suey here on March 30. There you have it: a double-shot of B.S. All that’s missing for the hat trick is a little Bobby Seger. Oh well — this’ll have to do.
