As someone that has seen them often, with the full lineup and missing members, in different cities, AND in the days pre-Dirty death where there'd be maybe 5 and the rest Killabees, they barely do Meth songs anyway. You get Method Man...where he names 100 Wu members like Clan in Da Front...and he and/or Street does Suspect Chin Music or Grid Iron Rap. That's it...I've seen Bring Da Pain only once. Songs he's on, they do without him. Rae, Ghost & Cap do Ice Cream without him, CREAM gets done with out him, But I've also seen RZA be the one that brings the most energy. I've seen times where Ghost goes on a rant...not recently though...and the crowd gets hype.
But I've also seen Meth & Red, and their energy is better...at least for the first 10 secs before a Philly crowd turns into a Philly crowd...head nods & adlibs.
I think the 25th Anniversary Tour was probably the best time for most of those up in arms to see them. They were all there, they also had a formula - doing 36 Chambers, then breaking off into the rest of the catalog.
