[after hearing Presley, Moore and Black mess around playing "That's All Right"] Whoa, whoa, whoa, whoa, whoa! Wait, wait, what the hell was that?

I don't know, sir. Just messin' around.

You been holdin' out on me, boy?

What do you mean, sir?

[laughs] Arthur "Big Boy" Crudup, for God's sakes. You know more of that music?

Well, yes, sir... know lots of it.

Damn. What the hell you been wasting my time for? C'mon! Let's back it up! Try to find a place to start and do it again!
