Dialogue imaginaire, quelque part au début des années 70…

Marvin – Hey!?

Ivan – Hey Marvin, Ivan, how ya doin’ bruh?

Marvin – Pretty good man, pretty good. How’ve you been?

Ivan – Doin’ well… Listen Marvin, I’ve been working on a new movie recently and…

Marvin – C’mon bro, what you need?

Ivan – See… there’s a scene, like… gangstas, you know… just cruisin’ downtown, in a Chevy… know what I mean? I need real cool music on this, smooth and funky, think you can help or somethin’?

Marvin – Lemme see what I can do, call you later.

Ivan –  Sounds good, bruh, thank you man.

Quelques semaines plus tard…

Marvin – Hey Ivan!

Ivan – Hey my man, I’ve been waiting for your call, bruh!

Marvin – You know about the music you need for your movie, check that out, I think you gonna dig it!
