Not sure which string of dates the Northwest Tour refers to, but Loverboy toured it's brains out in 1981. I saw them in Seattle, but they could be talking about a bunch of Canadian gigs--British Columbia & the like. Anyway, I got it in '81 and put it in a box-never wore it. It's a great looking vintage shirt which even comes with a "bonus" tag at the bottom, to make sure you know it's a Large, I guess! Best grab it quickly, eh?
