The tour sounds great. Predictably old men on Facebook are complaining about the lack of old songs. Knew that would happen. Years spent complaining about no new stuff then when there's lots complain about no old stuff. You just know that (unlikely as it may seem) released new stuff they'd just complain it wasn't F&L&A.
That's true, i've read relations from Wroclaw gig, guy was complaining there wasn't much of old songs played, among which was mentioned ... Black Planet, or, comparing to Machine Head gig that also played without support band, it wasn't last 3 hrs. FFS, less than bacterium, 1/64 wit.
The only time any such stuff should really register is if it actually affected or impacted upon the object of their ire. We can rest easy as Sisters fans.
