In a new interview with Greg Prato for Long Island Pulse, Dweezil Zappa, the eldest son of Frank Zappa.

Shortly after mother Gail’s passing last year, it came to light that there is a bitter feud between the siblings (Dweezil and Moon on one side, Ahmet and Diva on the other) over who is entitled to use the “Zappa” name and merchandising. In 2006, Dweezil began touring under the Zappa Plays Zappa banner. However, he was recently forced to change the name of the tour to Dweezil Zappa Plays Frank Zappa, before ultimately going by his own name.

Greg Prato: I - and I’m sure most fans - had no idea what was going on behind the scenes with the family until recently. Was this going on for some time?

Zappa: “Absolutely. If you want to hear more about it, the podcast with Marc Maron, WTF is airing now. I talk about how it all started and when it all started pretty candidly. This has been an issue since the tour began regarding a contract that my mother reneged on. I was arguing with her about that for years since she was taking 100% of the tour merch. That was never supposed to be the case. When she passed, the issue was never resolved and Ahmet and Diva decided to continue to do what she was doing. They said, “Unless you give us 100% of the merch, you can’t use the name ‘Zappa Plays Zappa’,” which led to the first name change. And then they created another argument to get me to have to change again. I changed to the name that my father gave me, so there is no dispute about that.”
