Interesting you mention Bruce. After Clarence's passing I had a lot of Bruce on (mostly his channel on Sirius), and every now and then we'd look at each other and say "how is he ever going to perform that without Clarence?" It will be different from when Danny passed, as Danny, while important to the band, was not a focal, visual, interactive part of the stage show. My guess is that Bruce hires a horn section, puts them on the back of the stage, and the set list changes dramatically. Time will tell.
