The thing I want to know is how he was strumming chords while his right hand is tapping! Was he tapping with his left hand as well?! Was he sneaking in a strum here and there?! I swear I heard strumed chords and I couldn't see how he was doing it. Suppose he has one of those kariokee robots hidden inside his sound box? Was he finger sincing to a prerecorded rythum part, or am I going blind?
