I could just be imagining it, but it sounds like someone is doing lines, in between songs... This is a soundboard, so who might be doing it, hmmm. Kieth, his vocal mike would be near the piano so he could do lines on the piano (but I don't recall him having vocal parts)? Maybe its the actual piano microphone with the top open a bit?
So, yeah, likely my imagination. I cannot figure out how that would have found its way to the tape... drummers?
Made me laugh to imagine this was the case, once again... in my imagination! decent show too but not played as well as the night before. But 4th show of the tour after a year and a half break... damn good, right?
