It's hard to tell what role Wolf is playing in all this (if it is in fact true). Is EVH pressuring him to write for Van Halen, or is it something they both want? Were they jamming on something of Wolf's and EVH said "yeah, let's use this for Van Halen", and Wolf doesn't want to contradict EVH? When you see interviews with the 2 of them, there is that weird vibe like a coach and his son, the quarterback.
It feels like EVH is trying to have Wolf "take over the family business" like it's a family restaurant or something. It's like he is using Roth to re-establish the brand and allow Wolf take over the name. For me, as someone that feels "Van Halen" was as much a creation of Roth's as it was Eddie's, that's really a fucked thing to do.
It's hard to get a good idea what is going on. But there obviously aren't any freshly written songs coming from these guys.
