Help with some show dates

[ZUMA]

I have downloaded 2 shows with different dates that turned out to be the same show on a couple occassions and I was hoping someone could help me clear up the discrepancy. 

1) A show from 7/22 at The Central Tavern, Seattle WA.  Is this from 1987 or 1989?  I have a show at the same venue labelled 7/24/1989 so I am a little suspicious of this one too.  Both are mostly OZMA material.

2)  The same show labeled as 2/27/1985 @ Club Wellingtons, Winnipeg, Canada and 11/25/1990 in Minneapolis.  The show is mostly Bullhead material with a few numbers from OZMA and Gluey Porch Treatments, so I am guessing the later date is correct.  I think both dates were played, but my show is from the latter.

Any help would be greatly appreciated.  Thanks a lot.

I don't know about the first show off the top of my head but the second show sounds like Minneapolis. That show starts out with Easy As It Was and plays material mostly from Ozma, while the Winnipeg show starts out with At A Crawl and is mostly early material with some covers.

Yeah, I have that Winnipeg 1985 show but was not sure of venue/date details.  I agree with you and thanks for the help
