Notes
A copy of this contract showed up on Ebay, showing GP $315,159. Guarantee was $60k vs. 80% net after expenses, plus $15k for sound and lights.
Gomorrah is devastating. There was some picking in the 5 minute range that made me catch my breath in what has generally been a background listen to the show.
