I could be wrong but I imagine things maybe went like this.

Dave is talking to Alex and they they laugh about how Dave suggested copying the punk band guitar and how that became such a big thing for Ed.

Dave mentions it publicly. There is push back, he doubles down now on it.

Here is where it's fucking dumb. No one wants to hear this shit, it's taking something iconic away from a hero to millions who is only dead a year. Secondly does he think the only possible corroborating witness in the room Alex is going to step up and take that away from his brother and then you add in the legal shit of it being a trademarked brand and so on?

Fucking idiotic from Roth. As a chess player he should have been able to think at least 1 move ahead on this...
