Excuse me, Bill. I speak Hack. Please allow me to translate.
"We play it just like the record." = "We play it just like the way we imagine the record might have sounded."
"That's not how it goes." = "Your talk of 'chords' and 'keys' is strange and it frightens us. Also, I can't play barre chords."
"We don't need to rehearse." = "Not even my mother will listen to me play. We've been kicked out of every building occupied by people with ears. Rehearsing and hearing how bad we sound hurts our feelings."
