Laura MusselmanWanda Jackson, at Neumos last year.There’s a killer bill at Neumos Friday featuring Wanda Jackson — the rockabilly queen whose Jack White-produced record, The Party Ain’t Over, was one of our favorites last year — and Sallie Ford, Portland’s up-and-coming stick of dynamite. We’ve got a pair of free tickets that we’re giving away. All you’ve got to do is email me at ckornelis@seattleweekly.com by 6 p.m. with the “WANDA + SALLIE” in the subject, and your name and phone number in the body. I’ll pick a winner at random tonight.Good luck!!!
