d) During the drum solo, he didn't even attempt to pretend to look like he's using the wah wah pedal for the part at the end of the solo.
e) The "I choose to live and to, lie, steal and... etc." part requires a sliding motion going down the neck to do the riff... his hand was in one spot.
f) He was holding Adam's backup guitar.
g) No sign of him clicking on/off the delay pedal(s) during the intro chords.
h) No sign of using the volume knob for the chord swells in the intro, or for kicking up the volume for the choruses.

I know it's a live show... and it shouldn't work that way, but you also gotta realize that it's not likely that the lead singer of a band would leave halfway through a song to get french fries and take his clothes off (which happened to be a cop's uniform). It's not just a live show, it's Tool!
