Hey, Prime members, you can listen to American Scandal add-free on Amazon Music, download the app today.

In a broadcast studio at Miami Top 40 station W-I-N-Z, a camera crew from NBC News prepares to film an interview.

They mount lights and cameras on tripods, tape cables down, carefully position boom mics.

Overseeing the activity, our NBC News Investigative reporter Brian Ross and his producer, Ira Silverman.

It's December 1985, and for months they've been trying to report a story on PAYLLA.

The music industry supposedly snuffed out PAYLLA in the 60s, but Ross and Silverman got a tip that it's back.

And now, according to their sources, the Mafia is involved.

The alleged distributors of PAYLLA are a secretive group of independent record promoters called The Network.

But so far they've declined all interview requests.

No one at the radio stations or the record labels will talk to Ross or Silverman on the record either.

And with no hard evidence and no eyewitness testimony, there's no story.

But now Ross has found a DJ willing to go on the record, a goofy bear of a man named Don Cox with curly brown hair and a bushy mustache.

He jokes with the NBC crews they set up.

But Ross consents that underneath his wisecracking facade, Cox is nervous.

He takes the DJ aside.

You okay Don? No second thoughts I hope. No way man. I got nothing to hide.

And Ross needn't worry.

Once the camera start rolling, Cox is natural, funny and forthcoming.

He even re-enacts a typical conversation between a top 40 DJ and one of the Network's indie promoters.

They'll go, here take this ounce of cocaine.

Couple of thousand dollars. Here you go. We can get you more.

By the way, I got this record I want you to hear.
