They were the gang that was selling drugs in the club before Frank re-took it over and who made the deal with Frank regarding the girl who had info.

Some thoughts of mine:
- how does that bar stay in business with that sad sack singer moaning every night?
- Ray, have you ever heard of Skype? I'm sure Chad has. What a hack trope, have the getaway locked down and then screw it up for no good reason. Heat called and it wants its ending back.
- The mexican drug gang…

I thought he was going for a Chinatown remake, without the lighthearted madcap sensibility.

Would you like to bet on whether Weird Al pays royalties on his songs or not?

They are selling shit. It's not fair use or parody.
