I doubt they were spirits. One or more of the following seems much more likely: Most or all of those disturbances were part of Sam's act; Pranks were being pulled by one or more practical jokers/hecklers (this IS a comedy place, so such things should have been expected); Faulty wiring/power outages (older building). Did these things happen when other comedians were up, or only when Sam was up? Chances are, these were deliberate distractions perpetrated by humans in mortal flesh, or there were problems with the technology at that time. The sources of some of them never being found simply means that those involved were either very clever, or the sources were hidden behind walls or other unreachable areas, or they were the result of storms, lightning strikes, or other acts of God. While earthbound spirits do exist and can reek havoc on our physical/material world, I just don't get the sense that this was the case with the events described in this video. Too many other logical explanations.
