Yeah, I think you might have a few folks immediately jumping in with the "shake! shake!" part.
Since I'm choosing to amuse myself with hopeful (and unlikely) notions, I'll toss out that it was not that long ago that U2 was willing to challenge its audience with unfamiliar songs. The Joshua Tree tour, when they were at the height of their "fair-weather, teeny-bopper-engorged" fandom, included things like Springhill Mining Disaster, a drastically reworked Maggie's Farm and Helter Skelter. You can't tell me that the majority of those audiences were familiar with those tunes at the time.
Perhaps old age will embolden them... then again, I'm not holding my breath.
