From section 113, right behind Page's rig, I can tell you that he was definitely teaching Mike to use the Moog. Moogs are complex little machines and have lots of knobs and dials. They are not intuitive to play and do take some practice. Seeing Page try to show Mike the ropes on that thing in the middle of a jam was one of my favorite Phish moments. They were both having such a great time banging out synth sounds! It was fun to see them so comfortable and excited about exploring something new.
