"Ralph dug back into his classical guitar training to come up with something the Devil’s guy couldn’t best."

Ralph is a good actor. He was able to learn how to ape the fingering on the fretboard and move his strumming hand in a convincing way to the audience.
He was instructed by a player-Arlon Roth.to play an "advanced "style of air guitar while holding the guitar. I had an instructional video on VHS with Arlon in the late 80's. Click on the "Crossroads" for fun facts.
